In the ISE, it would be nice to have some mechanism to be able to enter a cmdlet with all of it's parameters in-line, and then tell the ISE to collapse those parameters and their values to a hash table for splatting. I wrote rough add-on that lets you enter a cmdlet, choose the parameter set you want and the parameters from that set you want to splat, and then writes a snippet to the script pane. It's not pretty (it's using read-host and out-gridview to specify the cmdlet name and select the parameter set and parameters) but it basically shows how it would work.http://mjolinor.wordpress.com/2012/01/16/ps-v3-ise-add-on-for-splatting-updated/
