Would it be possible to have a "browser for http help interface" in advanced settings with a custom command line? If empty DO would use system default, if non-empty use given. Or maybe instead of just http help, DOpus could use that for all links it starts, something like "custom browser command".
Reason: I use Virtual Desktops a lot and when F1 is pressed, system switches to the first default browser it finds, usually on a different VDesk, to open a new tab then I have to move the tab to the VDesk DOpus is on. The workaround, starting a new browser window before pressing F1, then clicking DOpus back to open the help gets also pesky. With a custom command I can at least put some AHK in between or start another portable browser, which I have a ton of.
