1) the option to turn off tools in the mining mode. There's nothing worse than to be rocking a 20x combo when a dreameater essentially locks up everything on the screen and prevents you from setting up any more combos. For a tool that's supposed to help you, it really just seems to be a detriment instead.
2) It would be pretty rad if there was a tool that could change elements blocks from one type to a different type of element block. For example, let's say I have 2 fire blocks in a row. If I were to place this special converter box on the end of these 2 blocks to make 3 in a row, it would then popup a small screen and let me choose one of the 5 elements. Once I choose my element (let's say it's water), all of the fire blocks on the screen would change to water.
This would be a cool way to get some bonus combos. Also, on some of the level 8 challenges, I had to play them multiple times because even though I worked a combo chain for the whole time perio, I didn't get enough of the 280 target element blocks because they just didn't appear in the alloted time (ie. if I needed 280 water blocks, all that showed up was moon, fire, wind, etc). This would have been a nice way for me to turn the tides a little. Anyhow, thanks for reading!
I for one would welcome the ability to turn off the tools in the smith. I havent found them to be very useful when they pop up at random. Perhaps being able to use them in the mine like in the smith would be better - being able to place them with a double tap or something.
