Why yes there is, and I happen to use it since it's much more versatile than split windows or pen windows. I was actually going to mention that in my last post, guess I should have :laugh:

Just installing the XHalo xposed module gets the job done. One example of a nice feature it adds is that if you open up an app via tapping on a notification, no matter if your at your launcher or have any app running, the app will open up in a window on top of whatever app you're using at the time. If you long tap a notification, in addition to being able to open App Info, you now also have the option to "open the app normally", which is self explanatory.You can also select a group of frequently used apps and tick the option to display them in the notification panel, then you can insta-launch them in a halo window from anywhere. After installing the XHalo module, don't reboot yet because there's one more module you need (for full functionality.... Halo works w/o it, but the windows won't be resizeable or movable, like they're supposed to be, if you don't also install the module "FixVisabilityOfMultipleFullScreenActivites". Basically what that one does is it fixes the visibility of multiple full screen activities.

JK, well, that is what it does, but the effect is that Halo works properly. Before installing that my halo windows were always statically positioned in the center of the screen and the didn't have the bar at the top that allows moving or resizing the window. It also allows you to open multiple Halo windows, IOW, it just fixes Halo to act like it's supposed to. If your setup is similar to mine, and you "repurpose" the edges of your screen, and you don't really use native mutliwindow (I have a ton of apps installed, and since certain ROMS (Tweaked) auto-add all apps to the sidebar and penwindow launcher, particularly the latter would take like, a while, to launch. There's no lag whatsoever with this modified (and more functional IMO) setup. Anyway, I was going to recommend freezing flashbarservice (multi window) in Titanium of something. For me, doing that released a good chunk of RAM, so if you don't use, or are trying to replace the multi-window functionality, definitely freeze if you're not using. Additionally, the frees the long press back for reassignment to another function, should you be inclined to do so. I reassign the hell out of my hard keys, even adding an activity to just pulling the S pen out and pushing it back in.

Modified S Pen functionality is the last thing I'll describe about my setup, so that this time I can answer before you ask ;) I REALLY like GMD S Pen Control. I turned off air command, and have been working on and off on configuring that app with the goal of being able to launch anything (even obscure "secret code" menus) just by scribbling something on my screen. It's awesome, you just have to get into the habit of using the paths that you've configured regularly so that you don't forget them. So far I've just configured launching frequently used apps and settings toggles (the app also allows you to create, I think 5 launcher bars w/ 8 items (actions, tasks, shortcuts, toggles, a ton of stuff) each of which you can launch, of course, with a pen path).

So with my setup, I've pretty much taken the "Touch" out of the "Wiz".... wait, no, the "Wiz" ou... err, that's much worse. OK, first and last time using any variation of that description. what I'm saying here is that the TW "features" that I've replaced could be used on any device / ROM... so perhaps I've got my eye on an Nexus 6. Well, it was in my field of vision when I was playing with the N4 in the store yesterday (I can't resist activating dev mode on store demos... I mean I like to take a look at the settings there, but it's a thing.... if I pick up a demo model, I'm in About device tapping on the build #) on the N4 I was surprised to see that one of the first options was toggling the runtime between Dalvik and ART, but I didn't think the N4 was able to use ART yet, so I turned it on and the phone rebooted... I then saw the guy who's helped me out the most there was free so I went over to talk to him and ask a few questions and I forgot to check out the N4 set to ART before I took off. Really wish I did, but whatevers. I'll likely have my very own (hand picked perfection, totally perfect uniform display :victory:

So that was pretty OT, this a little less, but a complaint that I keep seeing about the N4 is lag with the recents panel launched. OmniSnitch seems like the perfect app to avoid that issue. For those unfamiliar, OmniSnitch is launched via a persistent (customizeable) half bubble / handle thing. A bar opens up (on any screen) and first you have a row of recently used apps. You can also assign persistent "favorites" that you can launch by tapping the arrow below the row of app icons, and you can immediately switch to a previous app or launch a favorite instanly - Lag + recent apps + OmniSnitch = complete non-issue. Attached a couple screen of how it looks (I don't think the app icons would be themed if you don't use Unicon, I'm not really sure about the general availability of this app. I actually pulled it off of the ROM that I installed on my Note 10.1 - so system app on tablet, but user app on phone. Works the same either way. I'd be happy to upload it, but don't feel like I should do so without permission from... I have no idea. Searching the Play store, the only result is called Fancy Switcher, which looks like a not so successful attempt to copy the app and (unnecessarily IMO) 'fancy it up'. Meh. So hopefully it's available on xda somewhere, but if anyone happens to know the dev if they could ask if they mind their app being shared in this thread, then write up a statement to that effect, both of you sign it (in blood), and send it to me via certified mail... I don't know. If people want it but can't find it, try to find out if it's FOSS, or GPLed or something, just post in here and if it's cool I'm happy to share :)
