I don’t think I ever actually posted about this. 
But it’s been live for a while, and I updated it a tiny bit today.
If you click the cog icon in the top right of the page, you can modify various settings.
Security - change your email, display name, and/or password.
Game - I may rename this to Racing, but right now all the settings are race-related so there’s nothing to separate. 
Should be self-explanatory, but if you want more details:
- Minimum Energy for Entering Races - only horses with this energy grade or better will show up on the race entries page
- Minimum Energy for Training/Workouts - only horses with this energy grade or better will show up on the workouts page (this will also apply to auto workouts, once I migrate them over)
- Minimum Days Between Races - this one is just a straight calculation between dates. So if you put 14, a horse will have 2 weeks’ minimum before they show up on the race entries page (regardless of energy/fitness/etc)
- Minimum Days Rest Between Races - this one will wait until a horse has this number of rest days (days spent at a boarding farm or at your farm) before they show up on the entries page
- Minimum Number of Workouts Between Races - this one will wait until a horse has this number of workouts before they show up on the entries page (again, regardless of energy/fitness)
- Minimum Days Rest Post-Injury - this one will wait until a horse has had this number of days post-injury (of any kind) before they show up on the entries page
- Apply These Minimums For Future Races? - if checked, this means these rules will also apply when processing future entries. So if you schedule an entry for 10 days from the last race but your minimum is set to 20 days, the horse will not be entered. Likewise for checking energy/workouts/etc.
Website:
- We have themes! There are a bunch of light ones, and a bunch of dark ones. You can pick a light and dark theme, and also override which one gets used (by default it tries to go based on your browser and/or computer settings).
- You can also set your language (in addition to using the flag icon) and your time zone.
Give a shout if you want anything added (@Andy I’ll add your results per page thing here at some point).
