Just a quick note that I have finished support for browsing, editing,
and reloading of custom feature forms and their init scripts, from
within QGIS, in my plugin, Plugin Editor [0]. I hope to do an early
release next week (Mac-, Linux-only).

I would appreciate any testing of editing/reloading of custom feature
forms init scripts, especially complex ones like you mention, Andreas.
I don't generally use them and need to do more testing.

*Does anyone have a project file with data, and a lot of forms and
init scripts that they could share?*

Currently the reloading method used is the same as what Martin
suggested. I will be trying to integrate a customized reloader.py
module, with dependency tracking, etc. [1] with this function as well.
