Feature Req: allow wider columns for DNG converter

With the PC version of DNG converter, it is possible to make the overall window taller and wider, but it doesn't seem possible to make the individual columns wider (or narrower).

I often use Bride Batch-Rename to make filenames quite a bit longer, such as _MG_1234.cr2 to 130614p_161234_MyLongDescription.cr2. This results in not being able to see the complete filename in the columns:

Thanks for considering this Feature Request.
