I never understood the obsession with having an uncluttered inventory. Surely everybody just uses the search function these days to find items that they need and don't actually spend ages scrolling through the pages of their inventories.
Yeah... that would be a good idea... but the search function does not work properly. Have been broken since the introduction of the +0.0x gear. They don't show up. Have been reported, several times, and InnoGames have claimed it fixed just as many times, but it is still broken.
Try searching for strength, and you will notice than none of the items using the "new" formula is showing up. Goes for all attributes and skills. And after a couple of years, I am guessing that either the people at InnoGames aren't intelligent enough to fix it, or they don't care anymore.
And why should they? The game is dieing, and they are just milking it for whatever they can now.
