The parameters dialog is good but lets make it excellent.
1. Have the ability to drag and drop the position of the parameter currently once created it stays there.
2 have the ability to lock parameters this would also effect the dimension in the sketch can not be deleted
3 add consumed by as a column currently to find out what a parameter is consumed by you have to mouse over every one to find what you are looking for
4 have a type drop down currently if you say create a text parameter then change your mind and want it as a numeric you have to delete it and start again
5 have custom categories of parameters currently having only 1 key is very limiting with the ability to filter by these
6 have the ability to add tabs with custom labels and colours and be able to drag and drop parameters between them
7 have the ability to search. The number of parameters can get very large
8 have a scientific calculator with all the inventor functions listed as well so if you type in this it can be entered in a equation box
9 be able to view parameters and parameter box by category colour and also sort and group by category
10 this maybe a big ask but can we now please have spaces and be able to enter any character
