1. Focus only on the value side of the grid. The version I have is very cumbersome to input lots of data into because of the navigation. You have to push enter to save the data in the current field instead of just being able to arrow to the next and after you push enter and arrow down the focus is on the left side instead of the value side. Sure you can start typing and it does go in the right spot but you cannot hit the delete key to delete the value and it just looks weird with the focus on the left... it doesn't look like you can just start typing.

 

2. Auto height resizing when multiline is set to true, or another property for autoheightsize. You can manually set the height now so you text fits when multiline but if the user resizes the split line it should resize by itself automatically instead of cutting off text.

 

If not I'd like to put in a request for them.
