Hi, thanks for the new forum 
I was wondering if there’s a plan to implement the possibility to move cells by selecting and dragging.
In LO you just have to click inside the selection and start dragging but if that causes a conflict in Collabora we could use a modifier key like Ctrl (Alt should be left for insertion, like in LO) or even activate a dedicated move tool in the toolbar (with e.g. a “four arrows” icon: ✢)
