Couple of updates...
Added an opacity setting option
There was a glitch or 2 in the new search box, it now refreshes grid properly and only uses filenames not paths in the search
Also now window can be resized and moved without the title bar visible by clicking bottom right to resize and between the search box and close buttons for move.
(updated archive in first post)
For some reason on my system after moving/resizing it seems to loose the height of a title bar on next open, cant stop it doing that
Otherwise it's cool
So you have written that new, must have program. Let us see it here.
