Hej Rune
Take your time! It is you who decide the pace of implementation and releases. Nobody else! All I want for Christmas is ... I will have to think.
My experience with adding tooltips is, that it is easier to write them, as the program progresses. Those missing can always be added later on.
Re units/div and grid structure we can discuss this later on. As it is right now the size of the traces may wobble a bit vs number of decimals of the measured parameters.
