AltGr for special symbols and windowizing maximized apps

[stiller-leser]

Hey there,

great app. Thank you!

There seem to be two things I can't quite figure out using smartdock on waydroid on my ubuntu machine:

1. How can I use the "AltGr" key for special character input like @ with smartdock? Disabling all the "Alt"-options did not help.
2. How can I turn maximized apps again into windowed apps?

Best regards, stiller-leser
