Yes There is a few things to wrap up, contributions have been collected and the main obstacle is doing the final phase without driving me to lunacy... Is there anything in particular you are missing?
I will keep you posted,

Actually, no. Probably, what I will need, is in 1.6-ext already. I would say: because I start to get into the code right now, I prefer to use the latest version.
My current investigation is not so difficult in general: heat transfer with heat source in connected solids. The problem - I use transient coefficients everywhere. I made Robin BC on the surface with groovyBC; physical coefficients I defined as fields and approximated as polynomials.
Current questions for me right now is:
a) how better to treat connected solids,
i.e., how correctly implement temperature-dependent conjugation (transmission) conditions. Before, I used setFields to set different values of physical properties, I used "harmonic" approximation of conductivity in laplacian but the results was worse than for "linear". As far as I know as mathematician, linear approximation, theoretically, leads to other solution than original. Not so big trouble with simple mathematical problems, but I still care for my future projects
b) how to implement BC with the second order of approximation
c) in distant future: how to implement flow of direct electrical current in metal with Joule heating. Quick search did not gave me awareness if this is already implemented or available.
