Oops, trying again.

* Use Epiphany, go to twitter.com. Save as Web app.
* Open GNOME Software. Locate Twitter among the installed apps. Remove it.
* Open Epiphany again, go to twitter.com. Save as Web app again.
* Epiphany will now ask if you want to replace the existing web app (that you just removed!). Apparently the app wasn't removed. Go to about:applications to confirm this. Yep, still there.

So gnome-software actually just sets NoDisplay=True when you uninstall an webapp so that it can store the history in the desktop file. Either gnome-software needs to save this extra metadata somewhere else (and delete the .desktop file on uninstall) or Epiphany needs to treat webapps with NoDisplay=True as not installed.

I think that Epiphany needs to stop handling web apps and defer to Software. We should look into making this discoverable from the Epiphany side though.

Allan, I think we probably want to continue to use Epiphany to create random web-apps, e.g. www.randomsitewedontcareabout.com -- unless you think this should move to software too? I'm not sure the correct fix here.

Sorry I think I misinterpreted the bug. I meant to say that Epiphany shouldn't include functionality to view and remove installed web apps, but it seems that this is a different issue.

Yeah, the issue is that Epiphany and Software have different definitions of what a uninstalled web app means. Software just hides it, while Epiphany removes all it's files when uninstalling.

I feel as if going to about:applications in epiphany or the software-center are both very unintuitive methods for removing web apps. I had recently added a bunch of web apps to my gnome 3.10 install, and it took google searching to figure out how to remove some excess ones I wasn't planning on using...which is not necessarily the best way to go about remove them.

Is it technically unfeasible to just be able to right click a web app from the activities overview and say "remove web app" or something of the sort? I imagine it would just take a new flag set in the .desktop file of webapps to label them as type=webapp, and a function built into gnome-shell to add a special command (in this case 'remove') to anything with that flag. I am not familiar enough with the code to submit any patches, but I would think it would just take a couple minor patches to epiphany for the way it constructs webapps, and a couple for gnome-shell for handling webapps.
