Toggle base64 padding
The user should be able to toggle whether base64 strings are padded. If padding is enabled, the current string will be padded accordingly immediately; if padding is disabled, its padding will be removed immediately.
This feature is exceptionally hard to implement because padding is added while typing, moving the caret to the end of the input at every keystroke. Not worth it in my opinion.
Without the padding, the base64 contents may be interpreted incorrectly. The padding characters must be accepted.
Turns out that the padding is not necessary after all. Still, I think suddenly removing the padding is not user friendly.
