BleachBit is a free software disk space cleaner computer system optimizer.
As most of my previous mock-ups, the idea is to refresh the design to follow GNOME Human Interface Guidelines. The "scan overview" is inspired in MacCleanse 4 (I think it's a pretty good way to present the results of the "Preview/Scan", much better than the current implementation). The rest of the program is pretty much the same.
15.10.18 - Updated the widgets to the new GNOME HIG (3.18).
14.09.30 - Clean button has been moved to the right (as some stated, one could click on the button whilst trying to use the side panel scrollbars) and styled correctly as a destructive action.
14.09.29 - Things have been moved a bit in order to follow the guidelines with respect to visual alignment spacing.
14.09.29 - First release.
