Eliminate feeds no longer in use

For those of you who have worked with PC-Horse for a long time, there may remain many own feeds that have been stored in various stables and horses that are no longer current.
They just occupy space and can easily be cleared in version 3.

Go to the main menu - select "control userdefined feeds" 

The program searches all stables and horses. If a horse is missing or if the feed has never been used, this is shown in a list showing the stable name. You can now erase all unused feeds.

Of course the answer may be this. Everything is OK.
