In some GUI's of other mods the quick inventory management buttons ('Sort inventory', 'extract', 'filter' etc.) get added automatically, and while in some GUI's it's placement is fine, in other it's off (visually unpleasing) or even on top of other buttons and slots the gui provides, completely ruining it.
The list of mods I know of where this is an issue:

• The Snailbox of the Snailmail-Mod is the worst offender of this, since it adds buttons on top of existing buttons
• In the Tetra-Mod, the general container management buttons seem to only appear at appearingly arbitrary numbers of pouch slots in a toolbelt. Also, if they actually appear, the buttons for the container ('filter' & 'sort') seem randomly placed within somewhere in the container. The buttons for the inventory ('shift lock', 'extract', 'insert' & 'sort') are fine.

I have found the "Ignored Screens" option in the config file and will put both of the above in that list and submit that as a PR later!
