Thanks for the suggestion! I may do that later, perhaps, if I can figure out how to do it. A tool may be handy, but has one big disadvantage: There are only so many tools you can have active at a time, so creating a new tool would eat up one of the few available slots. This could work if it was optional, but I'm not sure yet if (and with how much effort) it's possible to integrate both item and tool in the code.
Also, I've been quite busy with real work lately, and will be for a while. So I won't get much done on this mod in the near future. Bug fixes are one thing, but as it seems to work for now, I'd rather work on other mods where it's really necessary before implementing new features that will potentially break things again. I hope you understand. :-)
