Targeting Change suggestions
Disable Targeting of party members by clicking on them (Option). It often prevents or complicates mouse-click targeting of enemies. Targeting party members from the UI window is much better for targeting party members. Edit: however, mouse-click targeting when using spells should stay (reviving random dead people brings this up)
Add an 'Engaged enemies' Window (Option) to allow targeting and casting spells on them by clicking on their name in that window.
Remove Targeting of self by mouse click (Option).
