Increase the size of the Expression editor

I apologize if this is already in here - I thought I heard it was, but I don't see it upon searching.

Is it possible to increase the size of the Expression Editor in the dialog window, so that when a formula is longer than the box (which is usually), it'll wrap for easier editing?

For example:

To see the rest of the formula, you have to scroll, but it would often help to be able to see the whole formula at once.

Maybe something like what Excel and PowerApps has, where you can click a little arrow to expand the formula editor?

The editor as a whole leaves a lot to be desired. Help!

In this day and age surely we can expect a more user-friendly edit process than this! Come on Microsoft, you make some of the best software in the world, but this is atrocious.

Big thumbs up on the expression box suggestion. That's gotta be one of the more prominent sore spots in the authoring UX.

PLEASE bump this one up.  This is PAINFUL to edit.  I totally agree @jake  there are a ton of things annoying about the Flow environment (not being able to copy/paste actions, etc), but this is definitely at the top of that list.

I've resorted many times to just putting text expressions in the box (ie: 

Of course this means I can't have the advantage of the syntax validation, and help that the Expressions editor provides, though sometimes this is still preferrable.   

Making the Expressions editor multi line at a minimum should be done.  Would love to see some focus on usability.
