ksnip

Cross-Platform Screenshot tool with annotation features

Not tested on a device yet. What that means

ksnip in Breadstick

Breadstick runs Debian's own ksnip package for ARM64, the build a Debian 13 computer with an ARM processor installs, so ksnip should look and behave as it does on a Linux PC. On Samsung DeX, Floating mode opens it as its own window beside your Android apps, and Desktop mode runs it on a full Linux desktop.

Utilities work with the files in your Linux home folder and, once Device files is granted, with your Android folders too. More about utilities in Breadstick.
