Stylistic Set Substitutions

Thank you for both answers as they pushed me forward, so I’m playing around with the newly acquired knowledge.

  1. I only noticed (FC11.5 Pro), that - after setting Chaining Context and checked „calt” in the preview options – neither the Preview window or preview in the Open Type Designer show the alternatives ONLY where they are intended to be, but they simply replace ALL found glyphs that have its ss01 twin, with their alternatives. Does it work like that, or had I messed up something?

  2. Can I use Character Variants instead of Stylistic Sets in order to create Chaining Context? I read the thread about it (Stylistic sets v Character Variants in open type), but it appeal very theoretical to me.

  3. Another question is slightly off-topic, but it haunts me recurrently: can I put more/all Lookups into one Feature (just like on the attached image)? I mean, will it work properly? I’m not sure if the Features, with their default names (seemingly, strictly related to the Lookups/GPOS), are simply intended to encourage to keep the project in orderly manner, but on the other hand, once created Lookup cannot be move into another Feature, so I guess there must be a reason for that.

As for me and my - very possibly - barbaric knowledge at the moment;), the amount of („unnecessary”) nesting single Lookups in Features seem to be somewhat irritating, I’d rather put all the Lookups straight in the Default (language) upper folder, without any Features whatsoever.
