incorporate a couple of little upgrades

Hello I'm really enjoying the One calendar app but wondering if it would be possible to incorporate a couple of little upgrades for example the selection of colors for an appointment is not adequate for my needs wondering if you could add you know a bunch more colors available for various important appointment types and secondly would it be possible to make the band that goes across the date to be adjusted to be narrower so that more can be fitted on a particular day rather than if it fills up it's showing plus 1 plus 4 et cetera thank you so much
