[patch] Initial version for review.

1) additional button was added to status bar. "Show small records";
2) initial state of that button is off;
3) all events that are 15ms or less will be hidden until Show small records" is off;

Overall looks good. Please attach screenshot and fix comments!

I think you want immediate refresh here.

Comment this?

Comment would be nice. Something like: We show expand element for expanded nodes or for nodes that are collapsed and have unfiltered children, or we are not filtering.

This should be a function, not getter.

No need for _hasLongChildrenEvents here.

[patch] second iteration.

1) comment about _hasLongChildrenEvents propagation was added;
2) scheduleRefresh(true);
3) complex boolean expression was redesigned and looks much clear, no comments required I think.

No need to call _isLongEvent twice on the same record. I can optimize it while landing.

I'll land manually.
