[SpoolManager] How to use mid-print filament change

Plugins
1

The plugin describes "Support for manual mid-print filament change", but I couldn't find details on how to use it.

I'm printing with Prusa MK3S+ (single extruder, no MMU) and wondering how/when do I tell OctoPrint about colour change? My print is sliced with colour change on new layer: the printer pauses and beeps for filament change and after attending and loading filament it restarts automatically.

Anyone else using the mid-print filament change feature? Is it useful for this type of scenario?

Hmm, I think I've answered my own question. I didn't realise that when you change filament during a print you have a choice: commit the 'printed so far' to the previously set colour (what I'm looking for colour change), or change the whole print to the new colour.

Do I have that right?
