More of just something I'd personally like to see, but I'd love to have an option to hide 'retired' horses on the breeding tab.  Maybe just a checkbox so it could be toggled on the breeding page itself (or if easier an entire account option),

Reason:  I breed a lot of foals through my manchado project, and I retire a bunch of foals due to this.  Some of my horses look like they have extensive children (20+) when in reality it might only be 5 active foals.  Now, they did have those children, but ones without the genes I'm looking for are immediately retired and just seem to clutter things when I'm going through to make new pairs.  It just makes it a bit more difficult to look through my spiderweb of breeding connections.

For Example: https://horsefable.com/horse/1612832  -- 11 of the ~20 foals are retired from birth.   More of the active children will probably also be retired when I go to straighten everything out.    It would be a lot simpler for me if I could look at the breeding page and only see the ones that are active when I need to.

Sorry if this was suggested before.  I did a quick scan of the topic titles on the development board before I started typing it up and didn't see anything.
