In fact, I'm finishing roboform extension for K-Meleon.
I have really improved it and for 1.1.x, the extension is complete and after toolbar initialisation, the homepage, startup group or Last session is automatically launched.
For 1.5, I have two problems.
The first never can be solved, because it's a reentrance problem, and to be clear, it's impossible to launch id() commands to change the tab having the focus, and to close a tab during OnLoad event.
Passed this problem which must be treat manually (with a local URL explaining what to do), I have second problem, I'm able to launch homepage, and I'm also able to know which session is to be launched (last or startup), but there is no macro command to launch it. Without sessions kplugins, I think it won't be possible.
I'm starting on holidays at the end of the week, and for two weeks, so I'll wait my return to ask it to Dorian (which is on holdays this week).
