text: When a user opens a file extension that does not have a specific recommendation tied to it, we show the general notification that points users to the marketplace. This has the following flaws: Most popular file types are already covered by specific extensions, so what gets left in this experience is leftovers For most of the extensions there is no good extension to handle this experience. Thus opening the Extension page does not provide value This is adding un-needed pings to the Marketplace service Also we had a bug that this feature was not available in stable and only 3 users found it is not there Would love for us to get some telemetry on this actions to see if this is actually bringing value to users. If not, we should either: Remove this flow completely Have a pre-defined set of file extensions for which we show this. Checking with tags seems to be very faulty. In my example below there is not an extension that helps with PowerPoint files. !
Only of these notifications end up with users clicking on Search Marketplace ! When it is actually clicked here are the top extensions ! Thus I suggest that we: Remove this dialog Add explicit extension recommendation for and . Since those seem to be missing. what do you think?
Sounds good to me
Great. Ok, you remove the dialog when you find time, I will add the recommendations for csv and pdf. Or if you go on vacation, I can also remove the dialog. I am working in August. Thanks
Feel free to remove it in August, otherwise I can also do it in September. Here it is
To verify: a file with some strange extension. For example -make sure no notification shows up a .py file or .go file. Make sure you get an extension recommendation for specific python / go extensions
