Who's feeling visionary? SGF2 format

[bugcat]

This idea was discussed before in three threads in early-mid 2021:

Feature Request: Add Clock time on moves

I would like to see what the clock was at when a move was played so I can see how much time my student or myself spent on a specific move. This really helps with learning time management.

Store & display timestamps for each move

When looking back through a game it would be useful to see the timestamps for each move so that it is possible to see how long was taken between each move etc. There are at least a couple of use-cases where this would be valuable: I’ve known teachers in the past to make comments such as: “I see you only took 3 seconds on this move - you needed to spend longer considering this position rather than just playing the first move you thought of” When reviewing tournament games played over OGS for p…

SGFs playback by move time

Is there any program which can take an SGF with move time data (eg. from KGS) and play back the moves at the original speed? I found the idea being discussed as early as 2005. If not, then perhaps a new function for BesoGo?

It’d be best, imo, to merge all four of these threads together and pop the result into the Thread Guide.
