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 ...
