I agree with Gonzalo and Gary; this is just a makeshift solution for the time-being, so that activities like Speak, Chat, Terminal are not rendered completely unusable in ebook-mode.<br><br>Ideally, the best solution would be to have the OSK-appearance-and window-shrinkage on "automatic" and "tied-together" basis (without needing any manual intervention).<br>

OSK behaviour should be automatic, no user intervention (other than perhaps some manual view scrolling when there is no active focus to get into view). If we are missing cases (and we are currently), then these are bugs to be fixed and/or features to be landed (often GTK3 related upstream targets, but occasionally Sugar/Activity related patches). We made great progress in 13.1.0, hopefully we can finish off this effort ready for 13.2.0.<br>
