Haven’t been using multi-monitor setups since around 2014, but using multi-laptop setup quite effectively, thanks to wireless split keyboard(s) as I can switch between laptops pressing a combination of keys. Split keebs – sofle (mostly a backup option, 58 keys) and totem (current daily driver, 38 keys). Notebooks – various brands (used for different projects and things). Printer paper for sketching ideas/engineering designs. Books – whatever I’m currently reading/studying at my workplace. Sit-stand desk from ALDI (manual, or semi-automatic when I use my DeWALT drill with hex bit). Stickers on the desk legs – whatever my 2 years old fancy to put there, various brands.
