More suggestions:

• Other time limits, perhaps in a drop-down menu, including the current 30 second mode, 1 minute, and unlimited.

• Toggle on/off pieces (or at least make them faded).

• Toggle on/off letters and numbers at the side of the board.

• Toggle on/off coordinates for each square.

Since part of this exercise can be mental muscle memory, it'd be great to provide various levels of assistance before throwing new players straight into a 30 second timed challenge mode.

I'd be interested in taking a look at this (and the cool ideas from @rogersheu). It would be nice to break down into the smallest possible deployable increments.

To implement the initial feature request, I would envisage a simple toggle for 'Practice mode' underneath the timer.

1. The score and timer would be blank/greyed out and not change when the 'practice mode is toggled on'
2. The 'start training' button would be greyed out / disabled
3. The current mode would run as long as they want to play until 'practice mode' is toggled off

@benediktwerner Does that approach sound reasonable?

Seems reasonable. Probably makes more sense to just not show the timer at all though.

Do I understand correctly that one actually does need to use Scala to work on this issue? I initially looked into it on the basis of the no scala tag. I am happy to try and get my head around it but might be worth updating for future viewers / potential contributors.

@bigsee yes, when I took a stab at doing this myself I came to the same conclusion, more scala code is needed for this feature.

Depends on how exactly you do it but likely some amount of changes to scala code will indeed be needed. Most likely only to views using scalatags though which is pretty much just HTML.

Discussed in #10177

I guess so custom time feature shall be added in coordinate system

@bigsee @maxrosenb I'd be interested in working on this with you guys. I haven't contributed to Lichess before and it looks like I'd have to familiarize myself some with Scala, but this seems like it might be an alright place to start. Would either of you want to discuss over discord?

@johnboltum Sure - I'd be up for that. Short on time at the moment but still keen to contribute in any way I can.

@johnboltum @bigsee Would love to contribute to this issue. If possible, we can divide the work :p

@Bitsy-Chuck @bigsee @maxrosenb Hop on this discord server and we can continue discussing some more and get this done, https://discord.gg/WQVJtVfB

Joining now...

Are you guys still working this?

I'm working on this.

All the view is in the view.ts file. You need Scala only for translations, if you add one (probably not).

When he wrote that it was true, but yeah now you mainly just need Typescript to update the coordinate trainer.

OK, sorry.
