Eric,

Not sure which issue your were confirming.  The possible initialKeep bug
would  not be minor, if it's happening it could really make processing time
long for hfr and focus, like the 20s you're seeing. I'd vote to fix that if
it's broken. The other one (spinbox) is an annoyance, I'd lean towards
fixing it now, but if you twisted my arm I guess I could agree to wait.
