Point in Time Markers
Ability to add Point-In-Time Markers to any of the timelines.
I have a custom timeline that pulls from a local web source - it shows me my telephone logs - incoming and outgoing calls. Timelines work great for that because there is a start and a finish.
I want to also show when I receive and send SMS messages as well. I can already import them from my phone - but they are point in time - not duration.
Right-click -> Add Marker
Select the Icon, enter the time it occurred at, one or more tags, and notes.
It would also allow you to mark up your existing time by indicating milestones... or perhaps adding bookmarks for future reference ...

Another potential use for this would be for photos. If there are photos that are related to a given timeline, a plugin can be written that displays the date/time of when the photo was taken, and you can hover over it to preview the image on the timeline
I take photos of my odometer when taking business trips - then use the EXIF information embedded in the photo to determine when and where it was. Much easier than a vehicle log - but being able to integrate things together with Manictime is the challenge.
