How about MNT Reform or it’s Pocket little brother?

They get you

• Full mechanical keyboards, ortholinear if you’re into that
• Modern components
• HIGHLY modular and repairable - their main thrust is making messing with your internals accessible
• No sticky goo coating
• Cyberdeck aesthetics (esp the Pocket reform)

They do NOT get you

• Low price - you didn’t mention a budget constraint
• Thin. They are chunky kids, though certainly the Pocket reform has a reasonably portable profile

What plugins can you recommend?

I think the only markdown plugin I’ve used was for table alignment.
