Hi!
The search is based on individual tiles and LimeZu doesn't include those in the WIP updates. So I have to wait until a theme is finished and he adds the individual files in the main zip before I can update the search file.
Modern Office isn't too big - 5 themes with 1017 tiles total in the Singles sections across all resolutions (minute compared to the beasts of MI and ME), and Modern UI has 12 total tilesheets across all resolutions, then a folder of animations and then another for the Portrait Generator, which has 1203 total spritesheets in its folders, across all resolutions.
