This is one of those ‘nice-to-know’ features in Ableton Live. When I start a new project, it’s very common for me to drag the same plugins to multiple tracks, such as AUHighpass filters, with the same starting point cutoff frequencies. Yes, I could use a template, but I always forget about it.
Anyway, instead of always dragging the plug-in from the live devices browser, and select it and define the cutoff frequency, start with one plug-in instance. After that, select it and option-drag it to the next track where you want the same plug-in with the same settings. Continue until you have all the tracks populated with the same plugin settings you wanted. That should save you some time.
Same if you have a nice plug-in setup on one track, option-drag it to another track as a separate copy.
