Thanks for your suggestions!

1) I think the bug with < and < is fixed in the latest version. At least in most cases.

2) This is useful indeed.

3) -

4) I am extensively using your bot in writing a math project. I have several remarks if you are interested, but I don't know in which direction you are taking this. Is there a plan to actually compile the code within google wave (instead of using a service and replace with picture)? Of course, I don't even know whether this is technically possible from a third party application. The gray out feature is in the right direction. However, I don't want it in the middle of the wave so I end up deleting it after I know it works. It takes a lot of space and destroys the (manual) alignment of my equations. I just copy the code before compiling (ie hit done) and save them in my clipboard (using quicksilver) so I can use them again. I don't know if you can use this idea somehow. In other words, I think the optimal thing in this direction would be to somehow save the latex code without the latter being visible in the wave.

2 just means that you can write
$ $4
+5
+67$ $
over multiple lines, and it still gets parsed. This is especially helpful when writing matrices and such.

I’ll give 3 a thought. Thanks.

2) what do you mean multi line support?

3) is it possible to create some kind of aligned equation?
