My opinions, worth what you pay for them:
- SA-P is the best key profile I have ever worked with. SA non-profiled (all R3, for example) is a nightmare.
- The current backspace key needs to be two keys ( \| and ~`), The Backspace key needs to be (a 1.5u) just above the Return key, Control directly left of 'A', and CAPS LOCK moved someplace where you won't hit it accidentally.
- Win keys make great remappable combo keys on non Windows boxes.
- All keyboards need Super, Hyper, Meta, AND Alt.
- Glowy is overrated unless and until you can get custom 2-shot backlit-compatible keys. I wish I could find a set of Oblotzky ASCII caps (SA-P) in backlightable, but probably not in my lifetime.
- There should be two rows of F-keys [F1-12 and, above it, F13-24]. I'd say there should be a 2x5 bank of left-hand F-keys as well but I can do with having a separate keypad for that.
- Compact FF keyboards are HIGHLY overrated. I have one and even mapped out it's a royal pain in the left patella to use.
- Artisan keycaps are HIGHLY overrated.
- The "Media Keys" on keyboards, with the exception of mute and the volume knob, really need to just be standard switch keys above the NP if one exists; or in a vertical row of 4 on the far right if not.
- Print Screen/Scroll Lock/Break need to be moved down one row.
- The 1800 layout is off-putting (but it might be worth a look).
