Clip what's important to a small floating window, so you don't have to switch between windows or workspaces repeatedly. The window can become miniaturized or have its opacity reduced, in order to do not block what's behind it.
Best used with:
- "Always on Top" and/or "Always on Visible Workspace"
- A keyboard shortcut
On GNOME, go to Settings → Keyboard → View and Customize Shortcuts → Custom Shortcuts.
There you can set a shortcut to run flatpak run io.github.kelvinnovais.Kasasa
Note: On GNOME versions < 46, a dialog will appear to set up and take the screenshot, instead of directly using the GNOME's screenshoter; this may be inconvenient.
