This mod from Autologic changes the inventory and trading screens to show more items so you don't have to scroll down.
-- Better UI Mod 1.0 for S.T.A.L.K.E.R. - Shadow of Chernobyl -- February 2, 2009
If this is the first mod you are using, open fsgame.ltx in notepad and at the gamedata line change both variables to true (one of them is already true).
Extract the gamedata folder to your S.T.A.L.K.E.R. game directory and overwrite all files.
Create a backup of gamedataconfigui before you install if you want to be able to uninstall this mod.
Changes the games inventory and trading screens to fit more items in the windows without resorting to that sh*tty scroll bar.
Compatible with Oblivion Lost 2.2 and pretty much any other mod.
Compatible with Leandro's Widescreen UI. Leandro's Widescreen UI effects only widescreen monitors, while this one effects normal ones.
This mod is based on the UI from ABC Inferno, heavily edited and expanded to include looting corpses and stashes.
