I just tried TC 7.5 last night for the first time, and I love the bread crumb bar option, unicode support is great as well. I haven't checked any other options yet

One suggestion I have about it is:
When I click on the bread crumb bar to go to a higher level (higher being closer to the root) in the path I would like to see the lower levels grayed out instead of deleted (as long as my new path matches the start of my older path). this way the bar can work both ways as long I'm on the same route in the directory tree.
I've been thinking about this since i first saw the bread crumb bar on Vista RC, maybe theres's another issue here about this that I'm missing and that's why I never saw anyone implement it.
anyway if there is please point it out. and if there isn't I hope you'll implement this feature.
Thanks,
Elad Soffer
