Improved Assets Panel
– Filter assets by their type – building, park, intersection, education etc. by clicking on the respective icon on the top bar.
– Assets can be marked as favorite. Favorite assets can be filtered/ sorted separately.
– All assets can be sorted alphabetically, by last update time, by subscription time, by active state, by favorite state or by filesystem location.
– Assets in any category can be enabled/ disabled all at once.
Note: This mod is always active meaning the checkbox in the mods list for it will do nothing. You have to unsubscribe to turn it off. I will probably make this work in a future version.
