Hi
Is it possible to auto-resize the columns (Filename, Path, Tag, title etc.)?
I find that I have to do a lot of horizontal scrolling to check all the tags, and many have lots of blank space that could be trimmed automatically and that would reduce this.
You can press Ctrl and Numpad + to resize all columns.
That's very useful - although it would be even better if it didn't compress empty column headings so that they were unreadable (and there's no mouse tool-tips to show them either).
Also if there were an auto-resize columns option so it did it every time so you didn't have to remember the shortcut. 
For that matter, I didn't see this particular shortcut listed in the help or shortcut keys page.
But we still cannot just press CTRL + - so that we could see the previous layout [i.e. width]
