Direct Folders v4 - gone back to v3

I recently made the update from v3 to v4 (latest version) and I find it doesn't meet my needs in 2 ways:

1) When Middle-clicking v3 is very quick and v4 is very slow, I mean maybe 3-5 seconds slow. That's not acceptable.

2) The Shift+Click option for a second folder has been replaced by something else - I never really worked out what it was for. I found the Shift+Click useful but I could probably live without it (maybe).

Anyway I've re-installed v3.8 right over v4 and I have everything back the way I like it.
