Feature Request

EmuDeck Application Feedback

Elaborate on the feature you would like to see added to EmuDeck.

I am asking for 2 enhancements to improve the quality of the homebrew store.

Have proper indicators to show which game is installed and which game is currently not installed. Useful for game hoarders. As it is currently, I cannot tell which homebrew games have been installed without using the Dolphin file manager, as both the install and uninstall buttons are present, and there otherwise isn't any visual indicator showing which game is/isn't installed.
Add gamepad navigation to the EmuDeck application, as well as allow a way to add a Gaming Mode shortcut to the EmuDeck application, so that homebrew game management (among other things) can be easily handled in Gaming Mode. This may be deserving of its own issue.

Include any websites or links that may support your feature request.

Both suggestions are improvements to the EmuDeck application that do not require any outside reference to implement, so unfortunately, I have nothing to provide here.

Does this feature work on the Steam Deck?

For the first suggestion, it presumably should since the application is already aware of which emulators are installed, so this can carry on to detection of homebrew titles as well.

As for the latter suggestion, its goal is to improve the experience on Steam Deck (among other handhelds) anyways. It's very oriented towards the idea of Gaming Mode use.
