Why did they removed the matter tab? I liked the matter tab. Where can I see now how long it takes for a certain resource to be converted to matter? Guess I have to check the tech tree. Also they changed the water to matter recipe? It took too long but it was infinite matter; at least oil is still available.

This is due to the new system for generating icons and recipes. Now recipes are generated semi-automatically and you can see them all by opening the "matter-assembler". About water, I improved this recipe in the 1.4.8 update. Also, all ore is now processed into Matter at a rate of 10 units per second, so calculating production is not difficult.
