Cool initiative, UI can be improved.
The scroll position of the whole page (including the field where I'm typing) changes when you press enter with the first three commands, until until the current command is centered within the commands list
WPM is a strange measure when some words are -h and others are "user@example.com" including the quotes. Not like language doesn't have long and short words but especially with needing shift etc., this feels kinda weird and like it would depend a lot on which words you get randomly assigned. You can pick the longer duration to even that out, but you could also just switch to CPM and get more reliable results faster -- or so I'd expect
The highscores don't show the run's duration, aka the error margin
Theoretically this would have to use readline or whatever input mode the person is used to. Ctrl+P would put the cursor at the end of the previous command, Ctrl+W then erases the last word (until the previous whitespace), Alt+Backspace is similar but erases until the previous punctuation, etc. Not sure if that's all possible on web. For some reason it also didn't bother me though, although I'm a very heavy user of these and e.g. web KVMs and chat input fields (when writing a command to a nerd friend) keep tripping me up. I guess it just feels like a typing test and not "real". But it makes me wonder what "real" would do for typing speed
Going back to the previous command (with (ctrl+)backspace I think mainly) is something I kept trying to do though, also tripping up 3 commands in a row (notice typo -> autopilot-mode fixing it: backspace to undo the enter, type correct character, enter again -> now you have 2 lines wrong). Maybe backspace (or also arrow keys?) being able to go back to a previous command could be a setting so people are free to choose whatever is faster for them
The input field defocuses at the end, so then the default browser commands start triggering as I'm typing the remainder of the command (mostly that's just searching on the page and the scroll jumps to some random spot, but can also be leaving the page with backspace). Maybe the fix can be as simple as restoring the box' previous value onkeyup and coloring it as though it's disabled
Highscores are probably more fun if you see (or can toggle between) the latest submissions as well as the top month/year/all-time. More of a long-term thing, for now I lead one of the categories so I know the submission worked and that I'm amazing *pats self on back* (there is only one other person in that category for now :P)
I wonder how long it takes for everyone to get kicked out by a cheater though. Maybe there should be a cheater category that shows up once you hit >1.5×max(leaderboards), because people will want to try autotyping but you also don't want to give them ideas. Then they have some place to submit to without breaking the other highscores. I know that a lot of cheaters won't care but... I would :shrug:
Choosing e.g. Debian does not include Basic commands that I can tell, whereas of course on Debian it's not like you never mv a file. Maybe multi-selecting categories would enable people to combine it however they want, but then the highscore system is difficult so hm.
To reproduce... actually, I wonder if you can guess my browser and OS family based on the above :D
None of these are a blocker or big bother for me btw, it's just that I saw the invite to report UI issues/ideas and I can't help myself. I had fun using it, thanks for making!
Different durations have different high score lists.
