Not all containers have been converted to Legacy storage but they should be safe to store items in regardless. If I convert more storage in the future I will let you know in the update notes to empty those containers before updating. The displays in the basement will update to show items that have been placed in your museum. Please allow up to 24 in-game hours for the displays to update. This does not include the weapon cases and mannequins, as those aren't specific to any item and the player can decorate them how they please.
Installation
Use Vortex or MO2 to download the plugin and make sure it is sorted after its dependencies. LOOT should place it in the right spot.

I DO NOT RECOMMEND installing this mid-playthrough; anything stored in or around the house may become lost. If you must install this mid-playthrough, make sure to empty every container and every display, and be a fair distance outside the house before saving and quitting. If you need a nearby container to store things in, the tall wardrobe in the bedroom should be safe to place stuff in as this mod doesn't touch it.

Although I don't recommend it either, uninstalling mid-playthrough should be okay, as all items stored in the extended storage should still be accessible from the LotD safehouse. Anything in non-extended containers should be untouched.

Compatibility
The only mods this would be incompatible with is anything that modifies the Tundra Homestead. If you run into an issue, feel free to post it in the bugs or posts section and I'll see what I can do.

Known Compatibilities:

• Legacy of the Dragonborn - Creation Club Patch Hub (Tundra Homestead patch)
  
  

I plan to make LotD storage extension patches for other houses as well, so you can request houses in the posts section, though with no guarantee I'll ever get to them.
