blending clips on one track (and bugs)

i have 2 clips on the track, one run cycle followed by a pose, the transition is instant, it pops
is there a way to add a blend at the start of the second clip?
when i add an ease in duration (is there a shortcut for that by the way?) the animation still snaps

so while doing this video I found a refresh bug: when you have two clips on a track and the left clip is in infinity post extrapolation, recording new object in the second clip won’t show up until you deselect and reselect that clip

and a functionality glitch: when you have a blend you cannot record but the record button still blinks
either don’t blink and flash red to attract attention to the reason or turn off blend and allow recording - i’d prefer the latter

and another functionality glitch: when drag extending a clip, you can only hold, can’t loop
