I also have the Estel image but icons are not designed to work with it (Debian LXDE icon does not work with this image, even after Harmattanization). However, here is an observation/issue I experienced:.
In OOWriter, Gedit, Leafpad, Abiword, pressing the ENTER key on the VKB (I tested default, Swype, English Arrows) won't end the line to start a new one. I think the key is just not working as I can't do a websearch in Epiphany either, as I can't validate what I typed in the search field.
