[Fabio Zaramella (fabiozaramella)]

To me it doesn't look immediate for the user, also those big green buttons and the whole screen image looks blurry.

review: Needs Information

[Djax (parnold-x)]

No blurr here but I can upload higher resolutions for the images in the next days...
A argument for your first point would be good.
I thought it is obv. for everybody what to do. In the category "hot corners" with drawn hot corners to hover over the hot corner but maybe I am assuming too much.
Np to add a label or something with instructions though.
