Very nice work. The neat part is that it is possible to find out which textures one has actually used in a model. E.g. I realised that I had experimented with three different textures for door thresholds. Good being able to tidy that up. Filtering would be nice. Maybe especially if the plugin could filter out and list textures in use in the plan (my full list is pretty overwhelming). If possible, making the plugin work on walls/floors/ceilings and even models with built-in textures, would really make this plugin a must-have. ok
