Hi!

If you deselect "show folder thumbnails" under "Tree", does it get any better?

also deselect "show folder counts" under "General"

I cant reproduce your problem with my library as all is perfectly visible but if you uncheck those two it will be more room on each line.

P.s. I also get that litle arrow in my library but cant use it to change the width, however there is no need to for me as ive got plenty of room even when i cange my library to look like yours, must be some other setting that i cant find at the moment.
