I would like to change the reply composing window to add signature (and a few blank lines) at the top the email body instead of the bottom. Which files should I study and modify?
Thanks!
Already implemented as a user preference in the SVN, will be released as part of v.0.4.
But if you use the SVN, I strongly recommend patching it with one of the patches I posted to correct a glitch in the signature loading. See here:
