I currently own version 5.3.5 and have been using Studio 3T since 2016 at the latest. One thing which is "minor" but keeps being a frustration is the lack of "standard" IDE functions which my other development tools have. It throws me every time I inadvertently attempt to use them in 3T and cannot.

Indent Code. If I select a block of code and hit TAB I don't want to delete that block of code and replace it with a tab, I want it to indent it. and shift-tab to "De-dent"

Quote wrapping. If I select some text and press any of the quotes, brackets, braces, etc I want to wrap whatever I selected in that character, not delete what I've selected and type a single character. Similarly, if I type a single one of those characters without selecting something, I'd like the closing character to show up automatically and my cursor be between them.

Those "small" features would save a lot of time.
