Allow muliple files and/or selecting drawer for mailbox/import

I will accept that ticket as it makes sense. However, importing a whole directory will not be considered as you can perfectly select all files in the directory with one keyboard shortcut in an ASL requester which IMHO is a more safe approach as you might accidently select a whole directory and click "Accept" and see YAM ending up in trying to important all your files in C: or LIBS: or whatever.

Also note that you might simply concatenate all your *.eml or *.mbx files to one single file and the give it to YAM. It will then extract all mails in it. So as a temporary workaround you can do it like that until we have the time to implement your enhancement request.

Well, the "draer-thing" came to my mind cause one can e.g. drop old WBStartup to WBStartup-prefs and everything is imported.
As said it would have just been "a nice addition".
I will live happily ever after with the multiselcetion.

Thanks for the hint with joinging files.

(In [5761]) * YAM_MA.c: changed the mail import requester to allow to select multiple

files at once and start multiple mail file imports. Please note, however,
that for every file there currently will be a separate preselection window
opened as stuffing all mails from all selected files together will
require more substantial work. Nevertheless, mail import from several mbox
files are now possible. Thus, for the moment this closes #196.
