I use parameters a lot. I would like to have better acces to them. I don't like the current Fx button, menu as it hides a lot of my text (default is too narrow, I like to use long names that mean something to me so I don't have to guess what it is months later). I propose:
1) a side menu of parameters that can be customized to show the desired columns, which can then be dragged into the dimension dialog; and
2) an 'auto-suggest' (like all the search engines use) of your parameters as you type, continuously reducing the available parameters based on what you've typed.
