Thank you for your kind words.

"looks and runs perfect...Didn't have any issues or bugs, love it"

I do my best. I want to make it more material in the future, but I'm currently focusing on a big change on the infrastructure and add a nice feature that will be available for both rooted and non-rooted phones.

This could take some time, as I do not want to publish something with bugs, at least not bugs that people can notice. :)

"complete system integration"

I have plans to extend the integration, but this will probably only be for rooted devices. I try to make a balance on the time I spend on the app: performance, root-features, non-root features, UI, ...

As I wrote, now I work on something that I've neglected for a long time - the infrustructure of the app. This has kept me making better working features for quite a while, as I started the app from a hobby and didn't care much about how it really works under the hood.

For now, the app already has some kind of integration: it handles uninstallations and can even be the default app manager. You can try it on "Nova-Launcher" for example.

"permission manager"

I've read about it in the past, but couldn't find an easy way to do it. Hope It is possible under the short time I can spend on the app every day. For now, you can flash App-Ops (link here or maybe here). Never tried to do it, but you can. My app also shows a link to it in case you have it installed. I'm sure there are other apps that can do it for you

"options for clearing cache"

I have plans for this, but maybe not in the same way other apps do it. Something a bit more unique.

The reason is that the cache has a purpose (less network usage, faster access to data you've recently accessed) and the OS already manages it (or at least it's supposed to, according to the documentations). I will have those things in mind when I reach adding a feature for it.

The main reason for clearing the cache of all apps is to try to do something that takes a lot of space.

In any case, my app allows to clear the external storage data of apps, which is usually just as safe as clearing their cache (99% of the times, the other 1% is for apps that put sensitive/private data on the external storage, which is a bad practice), and it might also save you more storage than clearing cache (especially if the cache of the app is only on the external storage). It will skip essential OBB files so you don't have to worry about those.

"backing up apps as they are installed"

Actually I didn't think about it, but do note that if you install an old version on top of the new one (which is possible only via root), it can cause bugs on the app to appear.

Also, I can't auto-backup an app just before it gets updated (so that you could revert to its previous state), because there isn't such an event that the OS tells me about.

"uninstalling updates (roll-backs)"

This is already possible and available on the app, but only if the OS says that this is the only thing that can be done (instead of uninstallation). I am almost sure that the OS doesn't lets me to roll-back on any app.

"Keep up the great work. "

As long as I have the unique ideas I want to implement, I intend to. I also want to be #1 on the play store.

I started working on the app because I didn't like any app I've found, and it was quite an annoying thing to uninstall using other ways. I wanted an easy and fast way to manage my apps. Later people told me they want it too, and that I should publish it.

I do want to work on other apps too. I have some nice ideas for apps that do not exist anywhere. Just want time... :)

If there is a feature that exists on other apps and I wish to add it in the near future, I must make something extra. Something that will be better than theirs that they didn't think about. Something that will be worth it. Otherwise, I could just point users to try the other apps.

I've done this before. People asked me for backups, but since such a thing is still planned for the future (and will probably take some time), I could just recommend about other tools that do this (EaseBackup and Titanium backup).
