Every time using the "rezesion" tool (F6) it must be clicked on the toolbar to select the appropriate tool needed, even it is used multiple times. Would it be possible to make an option, so the tool isn't deselected when editing the pdf? For example for the marker it would be nice not having to click every time on the toolbar after marking a piece of text. For pop-up notes or inline notes I think it depends if somebody whishes to have it always in hand. So maybe making an option for every single tool?
Use double-click. Admittedly, that's quite un-discoverable.
Thank you Oliver! Good to know it exist :)
