Hi,
"...but that's not how the tooltip is supposed to work. Who wants a static tooltip when you drag things around, the idea is to show the user what number they're on, not what the previous value was :/ " Yes, you are right. This is the reason to implement "selectionStart/End" and "value" (those fields represents the current values and you can use them in the tooltip template). I notice that we haven't documentation for the slider's tooltip template and I will fix this problem.
"So you're pretty much saying we're not able to define where both numbers showup in the tooltip format then right...cant do "between {0} and {1}" as a tooltip." Unfortunately, you can't do it with the format, because of the ticks value/tooltip(as i mention in one of my previous replies). But you can achieve this functionality with template:
All the best,
