Sergiy Goncharov from the Mind2Chart people has been in touch with some additional details on this project planning add-in for MindManager.
"- there is a hotkey "Ctrl-G" that opens and closes the M2C pane, so there is no need to deal with ribbons;
- M2C is $79 for a single copy - available from the 'Try and Buy' page on the website
- M2C is working well with Mindjet Connect.
Now we're working on an updated version (1.3) which will have some great features such as resource costing and calendaring - I will keep you posted ........"
Thanks Sergiy - I am looking forward to the next version already.
