Had to smile at that nice diagram. One can see what you mean. Because it looked like such a potentially nifty PIM (Personal Information Manager), I downloaded/installed Tomboy - gtk-sharp-2.12.8-1.win32.msi
in 2009. I was amazed at the complexity of just that
installation. I was later reminded of it by this Dilbert cartoon:
With all its potential, and including that superb (possibly unique, so far) auto-hyperlinking of common/frequent references - redolent of Lotus Agenda - in the wiki notes, Tomboy
doesn't clear many of the bars on the Comparison of notetaking software - Wikipedia, the free encyclopedia
. For example, by comparison, MS OneNote goes right across the page in both the Features Comparison
table and the Formatted text features, others
So yes, excessively complex and possibly high maintenance - just too much trouble - unless (say) you have some other purpose for making use of that topological nightmare.
