when u add new action and the window with actions listed opens, u have to click in it to be able to scrool up and down.
would be nice that u could do that without clicking .
That's because the focus is to the search box in the top right. It's intentional, because if you get in to the habit of typing a few characters from the object/action/condition you want, you can usually find stuff much quicker than mouse - and even end up completely 'typing in' events without touching the mouse.
So if I change that I think it would annoy the pros who like how quick it is to do it that way...
