When trying to switch to DM channels the top result is sometimes unexpected.
Let me walk through an example, I'm making this up, but it's what "I feel" has changed.
Because of muscle memory, i would type things like ge+<enter> to go straight to a DM channel with George, but now I find myself in some random other george-ish channel DM'ing with someone I've never communicated with before.
I feel like it's not boosting/sorting based on who I've had communication. I see a lot of archived and other channels popping into the results.
