For some reason this doesn't quite work as expected. I like to have three tabs open in this order: Entities Table (individuals), Dynamic Tree, Aries Editor. The tabs are 'maximized' ie they all occupy the same (maximum) space. Whenever I restart the program the first and second tabs change place ie the order is Dynamic Tree, Entities Table, Aries Editor
Window->Save Display Settings shows the correct 'last backup' time/date.
This is on Linux Mint 19.1 XFCE 64bit.
