I think it would be great if BumpTop could display PDF and SWF previews in the 'Bump this Folder' view. I know this might be kinda hard to implement, but I think the feature would be awesome.
I noticed one thing when I watched the video again. The pie menu was kinda full of stuff.
Then I thought about this:
What if the pie menu had a sub-menus? So when you hover above an item, a sub-menu appears. If anyone has played Sims and remembers how the menu works there, that's what I mean.
That I can offer, on items:
1. Whether to add an opportunity most to choose it is necessary to sign the name of a file.
2. The opportunity of a choice of an anisotropic filtration and smoothing is necessary.
3. And why to not add one more kind of a desktop in the form of a sphere inside? And that it was possible to scroll it (many pluss from such kind, for example the big space for work).
