Lisp IDE Request

Is there a Lisp IDE, which would to use GUI editable blocks to visualize SEXPs?

I.e. pushing +/- would fold/unfold subtree, while insert/del would add/remove an element to underlying form, and pressing enter would edit it.

And cursor arrow would be bound not to chars, but to the SEXP elements themselves. Just imagine how many keystrokes it will save you!

I know there are Emacs hacks, but they are completely foreign and inconvenient, compared to real IDE.

It's not my fault that your shit pattern matching library is so noisy. And having to back-quote and comma-evaluate the variables which you can use outside regardless is pig disgusting.
