DPI/Resolution setting

[xaiya]

It's working great so far, except I was wondering how to change the DPI / Resolution setting? it's currently at 240dpi but I'd like to set it at 300dpi.
Normally in the export window I can select this next to the resize check box:

but with this plugin a lot of the options are greyed out:

Thanks in advance!

Since its just a digital image DPI does not exist really. DPI is just a thing in print. You can however change the resolution like in a normal export.
