There's a similar issue with Cunning Action. If you use the main Dash or Hide actions, you lose your main action for the turn. You can press the Cunning Action to open up the "Cunning Dash" and "Cunning Hide" (which are just labelled the same but a slightly different colour). I've lost count of the number of times I've accidentally pressed "Cunning Action" then "Dash" and discovered later in the turn that I've unconsciously pressed the wrong one and lost my turn.
It would be much better if there were only one Hide and one Dash button, and they did not consume your main action when you have Cunning Action (until you another main action, disabling your bonus action). Similarly, if you press Attack, then Hide and Dash should simply remain available when you have Cunning Action. It would be a better interface. And no need for the Cunning Action panel at all!
I don't think there's any downside to this. I haven't met any DM that required me to say declare my first Dash in a turn was "cunning" or not.
Sadly there are. Several. Not only as a Thief can you want to use bonus action on using an Item instead after having attempted an Attack, you may also try and cast a bonus action spell as a magic-wielder archetype for example. Plus, imagine multiclass comes later in an official way: that kind of "auto assumption" would severely break things.
I do agree however that interface has margin for improvement although I'm not sure what to suggest.
