Track paths in dayview
Filenames are listed; date and time is listed; but many filenames are generic, repeated, or simply not descriptive. Knowing where to find them will help to identify what project they relate to.
This would be great, but sadly there is no silver bullet for this. There is no way we can get file path from open applications. All we can do is rely on APIs of the applications to get this information, but applications need to support this and we need to write this for each application separately.
So currently it works for some apps, mostly office apps and few others which have this displayed in the window status bar.
I replied to another question but you might find it helpful: http://support.manictime.com/forums/222041-feature-requests/suggestions/18541291-tagging-by-folder-file-location
It involves a slight modification of your workflow but it's been a big help for us, even before we started using MT.
