[Enhancements] QoL Changes (if Possible)

[Xiseous]

Hi,

Before you see the ransom demands below, I want to say thank you for a new sideloading project that already looks great and has even greater support!

Made a small list of potential QoL enhancements that are in no particular order,

• If Possible change the message "app.localhost.direct" would like to install X to say "Feather" instead.
• When cancelling installation or after installation, make the dialogue box below fade out after 3-5 seconds (maybe configurable in settings? and maybe give them animations if there's time for that in the future, like when "sending manifest" inspired by Telegram's sending files)
• Ability to change app icon through settings by uploading photo via the photos/file app (would be better if possible via files)
• Dark mode icon support
• For Signed Apps: When resigning, allow to reconfigure the signing process again so that you don't have to keep a downloaded and not signed version.
• Setting to auto delete downloaded apps after X period (if you have to specify then 7, 14 and 30 days.)

Thanks
