Would it not be doable so as to add an choice to the itch desktop app to do that routinely?
Navigating Desktop-Steam’s file chooser on the Steam Deck is kind of a problem particularly, so even when it was obtainable solely on that system, it will assist rather a lot. In case you might someway additionally routinely configure the library picture, that will be unbelievable.

The itch app itself sadly doesn’t work in gaming mode. It will be neat if that was obtainable too, particularly if it might then add the video games to Steam with out going by way of desktop mode.
(Utilizing the identical executable detection that beginning one usually makes use of, that’s, since not every little thing has the .itch.toml.)

It largely works nice in any other case, with some delicate drawbacks with video games not supporting 16:10 or the native decision straight (which causes borders or not often some blurriness). Controls (in gaming mode) are much less of a problem, normally not less than one of many presets already covers them totally.
