I misread it as "maybe I should submit it for inclusion" and wanted to encourage you to do so by letting you know I will include it in the next version.
If you wish to make the change and submit it, you should base your work on the latest nsDialogs.nsh from Subversion. But even if you don't, this is not a fundamental change, so a patch for 2.35's version won't be hard to apply.
The best way is to submit a patch to
patch tracker, but a full file would work as well.
