a major improve i think would be allow the code insgiht to show up when typeing variables in strings like:

print("this {$varaibel}");

I more than 80% of the time i use the print statement i am using 1 or more variable and it would just be nice for it to show up automatically instead of have to hit shift-space like i have to now.

Oh, yeah, it always annoys me that I have to remember the variables by myself

What you need to remember is Ctrl-Space shortcut.

but there is no reason to not code variables when typing them in a string
