This mod adds 2 chests which job is to protect production/transport systems from clogging by removing items.
These chests should always accept new items pushed (e.g. via hoppers or pipes from other mods) into them but if they get too full some of their content will get removed.

Anything pushed into it when it's full will be deleted.

Advanced Buffer Chest

These instead of deleting new items will delete one 'slot' of most common one inside when they get full.

These ignore stack sizes, for example stack of dirt filling one slot is worth the same for them as one sword.

The most common thing here are barrels.

barrels in advanced chest

After pushing one sword inside first 'slot' of barrels got deleted to make space.

sword pushed

After pushing another one the sandstone got deleted as now it's the most common one. (Or rather, there is the same amount of slots used by sandstone as by barrels, sandstone gets prioritized as it's before barrels.)

pushed another one sword

After pushing few more golden swords will be the most common things inside, therefore they would be deleting themselves next.

pushed more and more swords

Note: chest only looks at names of objects, it's supposed to ignore any data, like how damaged is item or what enchantments are on it.
