And I don't even see a reason that all these different modes need to be visible at the same time. It also takes up alot of space.
There are probably many ways to make this more user friendly, but if it works for you, thats great
As the parent comment said, software should really be built for the user and not just so everyone and their children can use it (unless that's your target group).
Financial terminals don't have the super nice designs to it, but they are highly functional, customizable and fast. A lot of cashier terminals are still running on old hardware with bad designs, yet they are highly functional.
I think there's always room for improvement and with every change you'll see a certain amount of push back, but I think it's important to consider the user and not write "simplified" software, when you have power users in front of you.
It is also true that looking cluttered at first sight does not mean it's not good UX.
Just sticking to some proven standards, even from a 20 year old software book, can really enhance an interface. Right off the bat I can spot a half dozen instances where a text input could easily span to align with an element above it, but it falls a few pixels short.
