Text material is already added in server, as premium feature.. Also if object removing was possible, i would accept this only if it was added as premium feature too, but at the moment it is not possible. I remember those days when there were no retexturing and object removing, now when SA-MP added retexturing, texts, new objects, people are going crazy, like add that and this, water, resizing and etc.. In my opinion retexturing is already a huge progress in mapping, because now you can make literally everything.. What i wanted to say by this is that in my opinion object removing is not that important.
