Following notes were made with 1.5 Shackles from Winter Witch doesn't seem to work. Given fearsome + shackles combo any enemy unit witch fails the dicipline check should get captured, right? Switching back to your realm by clicking your realm's name in relations window doesn't work. Attacker doesn't...

Don't give a relations penalty when annexing provinces originally yours.

You should be able to see an units garrison value from somewhere and not rely on experimentation.

Relations screen should also color-code mutual defense.

Cooldown of spells should be listed.
