Allow manually pointing games to overlay

[mysteriousHerb]

Hi, it would be nice if we could allow the game on playnite to point to a overlay on steam vdf.
This would allow 1: use same overlay for different games, 2: (more importantly) allow I to change overlay name to steam appID, and get access to community controller layout.

It should already be able to do that but maybe not exposed on the UI. I am happy to play with json file if there is one.

It is currently not possible to change the name of the Steam shortcut independently of the Playnite game name, as the extension finds which overlay to open based on the name of the Playnite game. This is very inelegant, as such it will change sooner or later. The current plan is to store in a file the ID of each Steam shortcut corresponding to a Playnite game. Such a file would be freely modifiable. (You can get the ID of a non-Steam game by adding it as a desktop shortcut and looking at its URL). Maybe it would be better to instead store the name of the overlay... It would require more computation every time it is launched, but it would improve readability.

Either way, being able to automatically set the name of the Steam shortcut to its corresponding Steam appID would be an interesting feature. This could be made as a simple checkbox choice in the settings and the appID could be retrieved from any Steam link the Playnite game details may have. Such an implementation should be relatively easy to make. However, to improve the feature one should probably also be able to revert the name to a more reasonable one yet still keep the controller configurations...
