One of my most useful views here is a view I call "Where is it?"
It combines the main library database with the CD/DVD database and allows me to locate music and pictures wherever they may be, be it backup disc, local drive or audio cd, and it uses 5 expression based panes, a couple of which are quite complex affairs.
This view has always been quite slow to load, something I've lived with as once loaded, the view is oh-so-useful. With these latest optimisations, the view is loading in under two seconds. I never timed the view pre-optimisation, but let me tell you, under two seconds for this view is blisteringly quick, as is initial MC startup with three active tabs.
Quite often, after such dramatic optimisation, something, somewhere gets broken, but apparently, not so this time around. I've tried, but it won't break.
Top drawer work from the developement team on this one.
