I don’t think it’s an issue in general, anyway, it can be changed later on if needed. I would say, let’s go wild, see how you can push the new design while still making it feel like ubuntu However, that would be an argument in favor of putting the new theme only as an option for 18.04 (easy instructions to install with). Indeed, it’s a LTS, there is already quite some changes for people upgrading from the previous LTS, 16.04 (Unity -> GNOME Shell), and keeping the current theme with some small fixes (Ambiance) may help keeping some landmarks for upgraders on that LTS cycle? We can also offer the new theme for people who wants to change, collect feedbacks, refine and shipping it by default for 18.10? Just a thought!
So yeah, in summary, let’s go wild for now, didn’t want to restrain the possibilities and nothing is set in stone
Some values are gsettings parameters, so easily changeable. Most of the content should be changeable via the css anyway (by disabling
apply-custom-theme). I’m happy to help if needed there! But indeed, as long as it’s size changes/colors/look, it’s fully doable. For things hardcoded, we can work with dash to dock upstream as well to change/make parameterizable anything we need.
All of the above makes sense?
