The one that gets me is the fact that there's no user-editable combobox. There's a select drop down, and "input + datalist" (and that doesn't help when there's effectively 0 hint about what the things you can use actually are), but no way to have the two combined.

It's actually a little surprising to me since these are somewhat basic controls that have been around in UI toolkits for decades. It's in that weird sweet spot where the building blocks are almost usable enough to build rich applications, but it's just out of reach.
