The new version also shows the same problems like 1.6.3, but has additional ones. (One point is that it crashes when you try to open the Filechooser a second time.) Another thing i consider really annoying is that the fullscreen-button does not work, except if you have a keyboard connected (I have a Nokia SU-8W Bluetooth Keyboard.) I could upload the .deb of 1.8.0 as it is currently, but my guess it that you will not like it more than the current version (1.6.3). I will most likely not have time to work on it in the next weeks (at least in the next 4 weeks, maybe longer), so do you really want a version which is worse than the current one?
