Please add support for flatpak app add-ons

[vibrantleaf]

I've found a few times that I've needed to install or remove a flatpak add-on for a application and it would much nicer if I could do that from bazzar instead of having to do that from the command line.

You can do it already from Installed page

[vibrantleaf]

okay thank you i didnt know that was a thing, maybe that could also be visible on the 'store page' for better visibility the 'Installed' page the best place for someone would go to install a add-on unless they already knew that was how you would do that

especially since there would be no way to see what add-ons are available inside with out having to install the application

i will edit the issuse later if thats ok to reflect this information tomorrow

I think it would be better for add-ons to be also present in the main app page so it's obvious that the app has addons at all, maybe gray them out when the app is not installed
