"could not see any improvement over v5.1"
This review was originally posted on VersionTracker.com.
except being UB now, could not find any improvements on UI or feature set since v5.1.
Copying as TeX causes error very often and unstable, especially when there are some accute or accents applied. Sometimes crashes when pasting or typing TeX expressions.
You may just call it v5.x but defintely not v6.0 with this much changes.
Please watch out your competitors, MathMagic and MathEq.
