1. What is the difference between suspend and hibernate?
2. You add a trailing space in icesh.cc.
3. The numerical values for WMActions can't be changed.
4. The manpage for my loginctl (systemd) doesn't mention suspend/hibernate/poweroff.
5. What operating system is your loginctl from?

1.- Hibernate mode is a deeper power-saving state where the computer saves the system state to disk and shuts down completely. 2.- sorry for that, maybe i pressed Space unintentionally while editing the files 3.- i understand that, maybe replacing some option since exit and cancel do basically the same thing 4.- Arch manpages doesn't include it, maybe a difference between systemd and elogind, Void manpage include it 5.- i tried Artix and Void

Can you add a commit which removes the trailing space from icesh.cc and which keeps existing numerical values for WMAction intact? Then I can squash and merge and nothing will remain visible.

done, i removed actionHibernate = 174, from icesh.cc

No, you still have the modified numerical values for WMActions, which breaks compatibility. ICEWM_ACTION_HIBERNATE should be appended as the highest value. Idem for actionHibernate which should be an odd number two higher than the currently highest.
