Checkboxes should be selected after completion of action.

I would say this adds lots of complexity for little value, I would suggest closing as won’t fix. Consider deleting would have no rows to select for example. I’ll let Graber decide though, he might have another take

I understand the concern about added complexity, but I think this could be a useful special-case feature. If there are other operations that need to be performed on the selected content, this would save the user from having to select the same items again. It could also help users clearly see which content was updated. Just wanted to add that perspective while we wait for Graber’s input.
Attaching patch if someone can work on select All.

There’s the statement in the issue description:

Checkboxes should remain checked after action completion.

The question here is: why?
I think this qualifies rather for a custom project-specific solution.
I’d start from checking if you can hook into tempstore somehow and if not, just override the entire service and add your special cases.

If more users of the module will need such a feature, it can be configurable I guess but this is the first such a feature request since.. 5, 10 or how many years already and the patch will definitely not do.
