Rev timeline stack?

[David Glasgow]

Has anyone written a timeline stack/group?

I have looked at the software about, which looks luscious (especially  
Bee docs timeline) but it doesn't allow notes etc to be added, or  
vertical timelines with information attached to left and right  
'branches' of an event.  I can't find my veteran HC 'CaseLiner stack  
anymore, which over 15 years ago did what I want, albeit not  
lusciously at all.

(When I say 'timeline', I don't mean a Gantt chart, but the line with  
stalks and information flags, type of thing)
