After reading u/karthink's great post on simplified home-spun structural editing UIs, I've been playing with repeat-mode. It's trivial to configure a repeat map with a bunch of disparate commands all joined together by some entry binding(s).

The problem, as mentioned in the article, is that you can't tell when repeat mode is active. You just have to remember, unless you notice the message way down in the minibuffer. This contrasts with something like lispy, where you have visual confirmation at point that it's active (i.e. whether point is on a () boundary).

So I whipped this simple fix up: turn the cursor error-red while repeat mode is active. Working well so far.
