You have the right to suggest a change in their product. The problem with requiring PDS to change the EU4 interface is that not everyone agrees that they need to be larger, or have a confirmation. This means that, in order to please everyone, PDS would need to make many new UIs and that's a huge headache because it requires artist time and a lot of consideration from programmers to avoid graphical glitches. The option for a confirmation makes some sense, as an option, but the options menu for eu4 is pretty convoluted already.
I understand that mods can be hard to trust and hard to use in some cases, but IMO, EU4 works pretty cleanly with the Steam Workshop to make the experience very easy. You can disable a mod in the launcher with the click of a button even!

OK, I admit it, I used wrong word, I should write request, but I am not native speaker.
I decided to confirm my fear a moment ago. With the first country I checked DOW (with breaking truce) all stability consequences were hidden - I would need to scroll down to see them.
So IMO vanilla's UI is broken and not user friendly if such crucial (-5 stab) information is not visible on screen. And for newbe player it should be
exposed, not obscured. I also understand that even somewhat experienced players in haste may forget to check it. BECAUSE IT REQUIRES SCROLLING - more tedious IMO than clicking on confirmation.
I am not proponent of Confirm button everywhere, quite opposite, I think that some actions (like create core) should not have it, because I can revoke them without consequences.
I am not even saying that DoW should have confirm, although it would be OK, especially if I can customize it (=switch off).
I am saying that DoW UI is badly designed and I would like Paradox to improve it.
