1. Is it possible to disable the behaviour of switching tabs on dragging files? Or maybe include modifier (ctrl/alt/shift).
When i drag files to the quicklaunch and mouse is over other tab, that tab becomes active.
No it can not be disabled. Is that really a big issue?.. can't you just drag the files around the tab area. ?
2. Will it be possible to pass multiple files to quicklaunch buttons?
Depends on what you mean. Dropping multiple files as a parameter to an existing button, Yes
Dropping multiple files to be added as buttons. No..
3. Space key selects files/folders and calculates folder size. Is it possible to make it move cursor down like Insert does?
Their are plans to make them customizable.. But the problem is that the space and insert commands are a bit special and it is not easy to make to them user customizable in a good way.
