So we should be careful with those. Sure. This is a minor detail that can be customizeable, for example. > And even the "slow" mode-line packages still manage to maintain at least > 5fps, I believe. Nope. 0.2 sec is the delay that is barely noticeable. When "slow" mode-line packages affect users it is usually much worse than 5fps. (Though sometimes it is due to redisplay being fired frequently, not the individual refresh times being too large). -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
