The main new feature is a complete overhaul of
screenshot annotation tools. The old version (2.50) had
a complicated system of annotation tool settings in dialog
boxes and tabs and it was a quite difficult (while powerfull)
to quickly pickup and use some nice annotation tool.
In this new version (3.0), the complicated tool settings
were all removed from the screenshot application
and a new system of ready-to-use annotation tools
is introduced. That includes - instant preview of current
annotation tool in sidebar panel and a Library
of ready-to-use annotation tools with thumbnail listings.
The best part of all is - the (previous) power of annotation
tools customization is preserved - in a separate editor
(exe) dedicated to creation and customization of own
custom annotation tools.
