I'm making a Mac GUI for my application Mac Linux USB Loader and I'm not sure how to design my application's document window to conform to good UX principles. Here's a screenshot of the window:
The window is very cluttered and looks awful compared to other windows in my application. Basically, the intention of the application is to setup a bootable USB drive of a Linux distribution.
The two manual, obligatory fields are
Installation Drive and
Enterprise Source. These are two drop down menus; the former contains a list of USB drives that you can install to (basically, a list of drives that are plugged in) while the Enterprise source drop down contains a list of sources that are manually defined and added by the user here:
The remainder of the panels (the distribution name and version) are auxiliary and optional. Based on the filename of the distribution, these panels are automagically filled in with the correct values. Unchecking the automatic setup button enables the text fields where the user can change these values manually.
I was thinking about maybe dividing it up into a multi-pane layout or similar, with the basic installation drive and Enterprise source being on the default General pane and the other options being on a secondary pane.
What should I do to improve the window?
