FRANCOLA  I regret to say that I have now had a big problem with this app which the developer will not return my email on. It worked fine for a while, but now it has somehow left my menu bar in a state where it will not return to translucent! OK, I know that it is a BETA, but I would at least like some support for the product I paid for.

FRANCOLA  Nice app for menu bar, dock and stacks adjustment! It works well for me. One of it's most notable features is that it changes the menu bar without having to restart (the only app out so far that can do that). You simply adjust the opacity to your liking and the author has written a script that changes the menu bar and then logs you out and automatically back in! I sent my $10 and am quite pleased.

JDUB800  Nice idea and features - Not sure about the price.

Tried it out and it left some inconsistent artefacts on my dock. I then defaulted to the 'original' and it doesn't work correctly. I can live with it for now however. :/

All in all a nice idea, but with a couple of not-very-nice bugs at the moment - I also think $5 would be more palatable!

YMMV.
