raw data loader - select all in first box

[ercius]

Is your feature request related to a problem? Please describe. Just a simple usability improvement for the raw viewer.

Describe the solution you would like In the raw viewer the values default to 1 1 1 in each Dimensions box:

The cursor focus is initially on the first box and to the left of the 1. Can you 'select all' in that box so its easy to just start typing the size? When I tab to the next box the values are already selected and easy to overwrite.

Describe alternatives you have considered Wasting a sum total of 10 seconds in my life to press delete before I start typing. Ho hum... :)
