Indeed trying tactics in general can be unsatisfactory if you 1) don't let users enrich the set of tactics tried 2) don't let users prevent some things from being tried.

For your other issue, I am thinking about ways to hide hypotheses in the editor, without having to clear them in the actual code. This way they are still here if you need them, but they don't eat some of your precious brain space while they are irrelevant (huh) to your current work.

Thanks for your 2 cts! Maybe I'll think about this threshold idea now!
