if you bind the "switch next tab" or "switch previous tab" to the key binding of E, you are literally unable to make any other changes possible. This is because to confirm changes, you must either press E or click the button with your mouse. I don't know why, but the Apply button appears to be hardcoded to the e key, meaning no matter if you click the button manually or press the e key, it always activates the e key. What this does is makes it so you are unable to apply changes, as you will immediately switch to the next tab, making it so you can never confirm changes. The other problem is reverting to the default controls also does not fix this. This is because when you chose the default controls, it applies the controls but it does not confirm the changes. This means, as you can likely predict, you have to use the "apply" key once again, looping back the original problem.
Some simple fixes are:
Make it where you can change the binding for the "apply" button
Make it where when you go back to default controls, it automatically applies the changes, meaning you don't have to press the apply key.
