Review for Quick Folder Move by Stephen Montsaroff
Rated 3 out of 5 stars
Not a bad substitute to Nostaligy, which appears to be going away.
However, the incremental search (e.g. I type folderA and see folderA/SubA folderA/SubB) and/or having the folder path in the display would be really helpful.
For example, I have a number of folders named Admin (for work, for investments, etc). If I type in Admin, I don't know which entry is which.
