Anoying double quotes

[eried]

Why is double quote (") handled different than the other paired chars in some fields like the CAS?

I like how [], '', {} works in the calculator and in the emulator, you can delete one part of the pair without problems, and in the emulator you can just insert one of them, all that makes sense.

But "" are dynamic, and when you try to split a string or add quotes to a text it gets annoying, some quotes don't get deleted (but cursor skips 1 place and deletes the first letter) or the whole string gets deleted. Why?! And in the emulator you can't just insert one quote like in previous case, even inserting it as Char gets a double dynamic version.
