I was very glad to see this get updated with multitasking support. Previously, every time the app took focus it would revert to the As and lose any definition or screen you had displayed.
I prefer the new layout for the wordlist and entries, and there is now a back and forward arrow so that you can easily return to a previous entry. However there are bugs. Occasionally a definition gets "stuck" and no matter what word you select, the entry does not change. Only by killing the program can you use the program normally again.
One change was a huge step backward: the word form screen. Previously this was a nicely formatted set of tables that filled the whole screen. Now it is a drop-down widget that is far too small. The word form font is the same size as the entry. Thus, by default, everything is crammed together and too large. It is necessary to scroll the contents of the widget horizontally to see many entries. You can make the fonts smaller, but there is no way to set the font size on the form widget seperately from the entries. Big fail on this one, guys. Either go back to a full-screen view, make the word form fonts configurable separately from the entries, of make the widget much larger.
It the above issues are addressed in an update, this would be five stars.
