I noticed that for UnZip you switched from a dll to an exe (I get it, it's simpler for the 64bit plugin you don't need 2 unzip dll's), is it possible to call UnZip.exe from the %PATH% or does the exe need to be in the plugin folder (this question applies for the lister plugin too), I ask cos I have infozip's unzip in my path and having 3 or 4 copies of the same application is unnecessary plus a headache to update (although the UnZip hasn't been updated in a while) and at the moment this plugin complains if UnZip.exe isn't in it's folder.
Also I wanted to write that this plugin works with odf 1.2, is it possible to add a field ODF version (1.0, 1.1, 1.2)?
