Hey, I don’t have anything specific really, maybe just the UI size - I’m on a 14" MacBook Pro with the “More space” resolution, and for example the icons get tinier by every update
As for the colors, it’s very colorful, which is nice, but also I personally feel like it is a little bit of a cognitive overload, especially for things like variable icons, which feels kinda redundant.
The colors of the data feels like a great idea, maybe I just need to get used to it, but I’d probably bump up the font size, at least to match it with the current UI’s sizes.

I’d probably add a border to the bind buttons/elements, as now they got this transparent BG which kinda lowered the contrast a lot, on dark mode especially. The border would probably also add consistency as you use it all over the UI anyway.
For some reason my ui seems to have a base size around the UI of only 12px which is super tiny.
Here on the forum I have a 14px base size, which is what I get all across the web I think in most cases.
On my blog I use REMs which is also what I’m pushing here in the posts for quite some time, yet still many of the settings don’t offer this unit, maybe that might be something you guys also might want to consider.
I understand the font is not one size fits all, but a suggestion for the product might be to add a setting for users to set their own base font size for the UI. This might be the simplest way of handling this, without over-engineering it. Or just respect the browser’s base size.
I see you guys are using the :root { --text-xs-font-size: 0.75rem; }
which seems to be used as a base (at least judging by the fact that you use it in many places), meaning that you scale my 16px to x0.75 which is quite tiny for a base font.
