Maybe someone already mentioned it, but if not:

When selecting a character other than the party leader and casting a buff on someone, the whole party rearranges to stand behind the selected character, resulting in characters running around for no reason.

Suggestion: Program the "rearrangement" command after a new "go to" command is issued (when the user left clicks on the ground), so the party stays in place while buffing.

Not a big deal, but an extremely easy fix.

I'm sure it was mentioned before but it is apropos here: please implement buffing by clicking on the portrait...and maybe also attacking by clicking on the portrait in the upper left corner?

Hello good sir, can I talk you about our (potential) Lord and Savior, the thread about begging for better party controls?

Because what you are talking about is but a symptom of this broad issue (and yes, portrait targeting will probably get fixed).
