Hi.
If you're suggesting that gui-butler should be able to store its own credentials, that does not appear to be the case on macOS. If a locally-installed butler has not created its API key in ~/Library/Application Support/itch/butler_creds AND the app is opened from the Applications folder, gui-butler returns the following error:
Additionally, it warns to set the environment var BUTLER_API_KEY. When we do that, we get ...
Other workflows do not change the outcome. With a local butler and the API key unset, Wharf authentication proceeds as expected and the API key is written to the butler_creds file. My installed CLI butler at this point performs all tasks as expected. gui-butler does authenticate, but after itch authorizes gui-butler to access the account, the screen does not update from what you see above.
I have downloaded the source code, but I see this is all built in Javascript. I do have Xcode installed, but I have no idea what I might do to try and compile or debug this. Any chance you can give me a hint?
