Hi, I suggest to add German quotation marks to the Latex Bundle: This can be archieved by adding
<array> <string>„</string> <string>"</string> </array> << to Latex.tmbundle/Preferences/Miscellaneous.plist and Latex.tmbundle/Preferences/Smart\ Typing\ (Strings).tmPreferences
under the "highlightPairs" and "smartTypingPairs" sections in each file.
Please note that I have limited knowledge on how those bundles work. Applying the changes above worked for me.
Kind regards Johannes
