While the Toolbar Buttons selection has a wide variety of options by default, I would like the option to add single specific subfolders to the Toolbar UI. Example use case: I organize my protected Outfits folder by adding sub-folders within that main Outfits folder, but the Appearance/Outfits/Ctrl+O window does not respect the subfolder structure and only shows ALL outfits in alphabetical order regardless of the manually organized hierarchy as it appears in my main Inventory window. So, instead of adding the Appearance button to my toolbar or using Ctrl+O shortcut, I'd rather add the Outfits FOLDER itself to my toolbar so that it opens a new Inventory window as if I had selected "Show in new Window" on that specific folder within the Inventory window.
This would be a convenient quality of life option for those of us who need quick access to specific folders in our inventory more often, instead of relying solely on using Shift+Ctrl+i to open a new Inventory window and then navigating to the folder(s) we need.
