You should be happy with the Maemo version It's got more functions still .

EasyList-Harmattan was a total rewrite, because the EasyList-Maemo was written with QWidgets and MeeGo doesn't support the skinning of QWidgets.
I could compile EasyList-Maemo and run it on MeeGo-Harmattan, but the app would look like a desktop app. Very ugly indeed.
EasyList-Harmattan is QML only. It runs quite fast to my suprise, but I still hate the fact that Meego-Harmattan doesn't support QWidgets.
But even if it did support QWidgets I would have to do some redesigning, because I wanted the app to look native. As you can see from the screenshots the app uses native icons to create that feel.
