Tools Of The Trade Part 2: Hi-Logic MainType
MainType is a relatively new font managing tool (for Win only) that puts Extensis Suitcase to shame! I’ve been trying Suitcase for a while but finding and activating fonts with it was a major pain in the butt. You had to dig around in the preview list on the right and then to activate the font you once again had to search for the same font in the left side list (all with no mousewheel support).
After I was fed up with Suitcase I went with OT1 fontmanager for quite a while but this manager, while a crapload better than Suitcase, runs a bit unstable and doesn’t support some important formats. It also can only install/uninstall fonts but not activate them temporarily. There are also a ton of other font managing tools out there but almost all I’ve came across so far didn’t fulfill my requirements.
If you fell into despair so far because of the lack of a good font manager then I recommend to give MainType a try. I’m currently using the trial and when it comes to managing fonts on your system this seems to be the best choice currently (unless you prove me wrong and there is an even better tool that slipped my attention).

Thanks a lot! Currently I use suitcase but don’t like it too much due to the reasons you’ve mentioned in your post. I’ll try MainType.
Looks really good. I like.
[...] That said my Vista Experience went a bit limiting so far! Dynamic Font Management is a foreign word for Microsoft too! It seems nothing has changed about how Fonts are handled! They are either installed or not. I guess I hang a little longer with MainType! Let’s hope other companies aren’t sleeping and have drivers ready until release, even if they don’t loose one word about it. It would suck otherwise! [...]
I could not agree more, I’ve been sick of Suitcase for so long but every alternative I’ve tried has been flawed in one way or the other. This is what I’ve been waiting for. Excellence.
