Hi Mouser
I think it's a good idea.  Personally, I like the big gaps as it simply makes the bar easier to "read" at a glance. 
I don't need white.  A ready-made transparent one would look good and save people having to make their own.

Hello Mouser
I did try a few things to get the file association working last week and gave up, deciding the solution would show itself at some point - it was no big deal.

All of a sudden, I'm happy to report that the file association is now working in both Explorer and LBC.
Why ? No idea.  It didn't work last night, but this morning it does. 
There hasn't been a Windows update of any sort for several days, but something has started working.

LBC is now looking good.  :)
There will be lots of people who have used Microsoft Office Toolbar from 1997 or 2000 who suddenly find that it doesn't work in W10.
LBC is the best alternative (actually the only alternative) that I've found, albeit more awkward to set up but much more powerful, of course.

No, I've just restarted again and no change
