Help/instructions in UI #635
Description
There are some features that are not obvious for users and we need a way to make these more accessible. Examples are:
- Creating a ROI plot (consists of multiple layers/plots)
- Creating a sliding window plot
Some of this can be solved simply be defining templates, i.e., by avoiding that a user ever has to do it themselves. However, we should still consider if we can add some help or instructions within the UI, i.e., by adding more tooltip icons, or a tab with help/documentation.
