Track multi selection delay destroys "snappy" user interface
This is not excusable from a user interface perspective: Locus MUST NOT DELAY when simply selecting/unselecting checkmarks. Not even a tenth of a second. Nor must it put up working requesters or dim the display. Nowhere. Never.
Multiselecting must always be instantaneous, no matter if the track has 30 points or 3.000 or 30.000. I dont really know whats going on here in Locus behind the scenes, but why are there such time intensive calculations required for simply selecting items in a list? I cant remember this being the case in earlier versions. Can you not revise the program logic a little and try to do those calculations elsewhere?
