I've pitched the idea of adding MindManager support to execs at both companies. The folks at MindManager have indicated that they are willing to play. I hope that the folks at X1 decide to play, too; I think MindManager support in X1 would be a powerful addition to their product.
For now, X1's still on my "must watch, but wait and see" list.
Meanwhile, the new Desktop search toolbar from Microsoft apparently allows plug-ins. And, there's a plugin for Mindmanager! (ComputerWorld | add-in)
A while back, I blogged about how my ideal desktop search tool would include support for both MindManager and Lotus Notes. I wonder if we'll see a MSN Search toolbar add-in filter for Lotus Notes?
If they did, I might switch gto MSN. My clients might, too.
