Hello and thank you for this awesome mod!
While playing I thought of some things that would be really helpful in my opinion.

1) Would it be possible to have a "stack" button right in the player's inventory, which would stack things to nearby chests without having to open them? Like in Terraria? I don't know how difficult that would be, just imagining that since you have already made the functionality for that, maybe it would be possible to call that function for all nearby chests.

2) Extending upon the idea above, it would also be nice if you could craft things without having materials directly on you, but on nearby chests. Maybe something like tricking the game into thinking that nearby chests are your inventory or something?

3) Another great quality of life thing would be to have small tooltips showing the name of a chest when the mouse is over it (including the ability to turn these tooltips on or off). That way you wouldn't have to open them to see what is inside.

4) I think the button size of the stack button is a bit small. Maybe it would be better if it was a button like the "Take all" button, big and easily clickable.

5) Lastly, I was thinking that it would be great if next to the already existent stack button on the bottom left of the chest, there was a "stack category" button, that would put items of the same category in the chest. For example if I use a chest to store seeds and I find a new seed, it would automatically be stored in it without having to do it manually first.
Two ways I'm thinking of would be for the algorithm to check the categories of the items already inside a chest or

6) Have a drop down menu with existing categories of items. They could be added to a chest like tags, eg this chest has the "1-handed weapon", the "seeds" and the "container" tags. Maybe the tags could also be visible in the tooltips of the idea above.

Thanks for your time, I hope you liked my ideas and that they inspired you somewhat.
