Oh, and now the edit button for sims is enabled, also when multiple sims are selected (fixes #2140).

Functions as described with no anomalous behavior found.

I do have one concern. If a change is accidental, there is no way to cancel that change. I would have the esc key cancel the changes, rather than confirm the changes.

I get your point, but that would be counter-intuitive to the workflow of component editing, where pressing the escape key also applies the changes. I'm also very much used to this workflow from other software, as I don't always want to move my mouse over to the close button and click it. Pressing the escape key just accelerates my workflow + it's aligned to the component edit workflow.

Ultimately we could have a cancel/OK button like in the component editor.

I do think something is needed to cancel an accidental change, perhaps as @neilweinstock suggested.
