I posted links to the Mavis Up button before, but I didn't think it was worth $5 for a shell extension with a few UI bugs.
However today I found something that cures practically all of my Windows 7 explorer-related ills:
- Adds an 'Up' button
- Brings back the icon and folder name to the window's title
- Restores the "Size" field functionality of the statusbar and also shows disk free space
- Runs as a ~300KB shell extension rather than a separate process
Along with a TLB installation I can safely say that I'm satisfied with my Windows 7 installation. I now see no need to shell out for DOpus, though I don't know how well this runs under classic mode.
