selset on ompty click doesnot clear

hello all.

At first, thanks for developing native cad for linux. It is great job. I was trying latest alpha builds on some small drafting tasks and there are some my perceptions:

- layout tabs are not visible (but are clickable and works ok) + some small tuberosities in displaying entities (gentoo, ati, free drivers)

- im using efficient selections by "click-drag-release", it works ok when i select some new selection set, but when i click on nothing, or drag selection window on empty backgroud, old selection set should be cleared, but in bricscad stil persists until something new is selected - is it intended behaviour?

- can i set somewhere "shortcut underscore letters" for snap menu, which is binded to middle button?

- can be (or will be) customizable mouse click/ctrl-click/ctrl-shift-click?
