2nd vote for Espanso, it replaced the outdated AutoKey for me and has been working great ever since.

With the gems’ forms being projections, I’d think that Peridot calculated all that by looking at Amythist’s gem, not her body.

Use Tabby. It is, by far, the closest to a Linux terminal experience. Likely because it’s cross platform. I say this as someone that absolutely despises Windows terminal experiences.
