@heluecht That will mean 2 clicks to switch a timeline instead of 3. Does that really that important?
But if we would creat a one click switch between Default timeline and any second timeline, you could simply make e.g. "Everything" your default timeline and if you need, switch to Mentions and back to Everything in one click. Switching to other timelines would still require 3 clicks. This looks more convenient for people, who uses not more than 2 timelines most of the time?!
