I see that when you try to add new experiment, there are no color difference between groups of metrics (easy fix I guess)

We actually just redid the UI for this last night. We tried using colors for the tags, but it got really distracting and didn't scale well. We switched to using a dropdown instead to select a group of metrics. We still have some work to do on this UI though

ok. I also want to ask: is it possible to understand somehow, WHEN this chance will be about 90%, for example?

not currently, but it is something we want to add

will be interesting also to read state (I mean what methods you used) about this
