Where did the other category icon themes go in SkyUI 5?

They had to be removed, because they're no longer maintained by their authors and icons for the crafting menus were missing.

Can I just upgrade to SkyUI 5 from an older version?

Yes. Just install the new version over the old one. You don't have to start a new game.

Can I downgrade to the old version again or remove SkyUI completely?

Yes you can, but when you save your game with a mod, you should not remove the mod from that save later. What this means:

• After downgrading SkyUI, go back to a savegame you saved with the old version.
  
• After uninstalling SkyUI, go back to a savegame you saved without SkyUI.

What is SKSE and why do I need it for this mod?

The support for UI modding without SKSE is very limited. No text input, no MCM, no extended item data, no active effects icons, no new favorites menu, etc. Basically, there would be almost no features left if we made a non-SKSE version.

How do I install SKSE?

Download the installer from the SKSE homepage[skse.silverlock.org] (beta build 1.7.3) and run it. In the past, some additional steps were necessary to start Skyrim with SKSE, but the newest version is now automatically loaded by Steam. So you just have to install it and you're done.

Where is the weight/value column that is shown in some screenshots?

It is hidden by default, but you can enable it in the column list. The column list is shown when clicking the top-right gear icon:

How can I access this column list with a gamepad?

Hold Order for one second (default: LT).

What's the meaning of the small icons after the item name?

Where is the Mod Configuration Menu (MCM)?

In the pause menu:

Where can I learn more about using the MCM for my mods?

Check out the official documentation[github.com].

Is there going to be a standalone version of the MCM?

No, but what you can do is use this mod called SkyUI-Away[www.nexusmods.com] to override all SkyUI menu files except MCM with their default versions.

I'm using a gamepad and there's no location search in the map menu. A bug?

Sorry, but for technical reasons, this feature only works when using mouse and keyboard. The directional keys are used to move the map, so scrolling through the list doesn't work, which makes it useless.

What are the icons in the top right corner of my screen?

Those icons represent the active effects on your character.

What do the icons mean?

Most of them should be self-explanatory, but here is a list for reference:
