It's a serious issue. Several things really
'SAVE and Continue' would be a VERY useful
Seeing the whole process (of making an Observation) in PREVIEW mode would be valuable
"Your work is not saved, would you like to save it", would be lovely.
I have had loads of disasters by (carelessly) dropping a picture OUTSIDE the allocated space - the whole process fails, all the work goes.
We DO have a wish list** which NObody discusses anymore and it's lost in the dust of this place. It is hopelessly inadequate, compared to the very long BugList and the suggestions made by the departed ZA emigrants and ALL the work done before during the 2017 recode by a small panel of Testers (I was one and still feel ashamed).
