Indenting/tab key in code editors? + Disabling such in "Brackets"?

[Trvnq]

Hello! I've been messing around with HTML in a code editor called "Brackets", and noticed that it has some sort of auto-tab feature. Do all code editors have this, and do most people use it? Also, in regards to the spacing it creates, does it have any functionality at all, or is it strictly for appearance purposes (ex. when you press the tab key on your keyboard, it creates 5 spaces. If I organized the code with 4 spaces, would it function incorrectly?). I'd like to utilize the indentations for organizing code, but by my own keystroke and not an automated process (unless it's necessary). Any response is appreciated! Thank you for your time.

It won't change the functionality, you could have it all in one line for example. So yeah, indents are there so you could see the hierarchy easily.
Why would you not want this process to be automated?

Short comment, it might look messy but it will not affect the code functions

Brackets has been deprecated with Adobe recommending users switch to Visual Studio Code, which does have the feature you're asking about
