Neat stuff:
* Lots of options for numbered items 123, ABC, abc, rounded, circle, and various transparency levels (this is really great)
* Highlighter pen
Missing bits:
* Speed bubble doesn't automatically include a text prompt (have to add it separately)
* CTRL+Z to undo
* Easy upload to image hosting services like Imgur
* Batch operations
* Image editor is really just an addendum tool for screenshots, which makes sense as the same company sells a program called Screen Capture Pro
Status: not at all portable. Writes settings all over the place, automatically sets itself as the default graphics viewer.
