Biggest improvement in QText 3.40 comes in area of printing. Code that traces its origins probably from very first (text-only) version of QText was finally adjusted to properly support Rich Text Format.
With ever increasing number of folders there was need for some sort of navigation helper. Pressing
Ctrl+G will enable you to quickly search documents by name. That should make searching for particular document among folders a breeze.
Those using QText for journal will be happy to know that
Alt+Shift+T are finally supported. Upon press you will get current date and time inserted into a document.
In addition to general bug-fixing that was done I think that everyone should have a reason or two for upgrade.
