Request: Move inventory window
 

This may not be possible as it looks like the other add-ons that can move windows seem to be able to move everything but the inventory/character windows but I figured it was worth a shot. I'm on an ultrawide so these windows are super far apart. It would be great if I could adjust them or find an add-on that moves them closer together. Thanks in advance.

No, there is no easy way as there are so many addons relying on the position, which would break then in the end.
Also it would make vanilla UI buggy. I tried once to move the frame and after that hell broke loose :p

You should try additional addons like
Inventory Insight from Ashes
It provides it's own movable Inventory frames + benefit: Show all other toons and banks bags and items too.

For ultra wide screens or multi screen setups you can define overscan offsets in the UserSettings.txt and make the UI take only part of the screen. Check out my answer on this old thread.
