I have created/modified a patch to enable intelligent signature placement in the event of a user wishing to put their signature above quoted text. Reproducible: Always
Created attachment 134720 [details, diff] kmail-tofu.patch This is the top posting patch (called 'tofu' as it was originally called such and is apparently a german acronym).

Created attachment 134729 [details, diff] kmail-tofu.patch small fix
Please take that patch upstream if you must. "Text oben, Fullquote unten" (tofu) / "Text above, full quote below" is excessively annoying and something I definitely won't add.
