I fully agree. In the meantime, I did list a few workarounds for some of the issues you have below, which you might find helpful. > > On Wed, Sep 23, 2009 at 10:57 PM, Pavel Solin <so...@unr.edu> wrote: >> Hi, >> by now I spent many hours with programming inside the >> web notebook, so here are some suggestions how to make >> this kind of work more pleasant: >> >> (1) Coloring source code would help a lot.

There is a way to do this but it's not trivially straightforward yet. (you have to use <img src="cell://image.png"> and then you can put images anywhere using arbitrary html).

Use shift-enter instead of clicking Evaluate. 2. Use %hide at the top of a cell to collapse it.
