I'm not planning on adding these - the menus are already getting somewhat cramped. The menus are all defined via the XML files (in /usr/share/FBReader/default) so you can add/remove whatever items you like.

There seems to be a bit of an issue in the current upstream version with CSS. Sometimes the styles either don't get applied or don't get removed. It's a horrendously complicated bit of code though, and I haven't managed to figure out what's meant to be going on in there yet.

Damn - I hadn't realised that adding that had pushed off the fullscreen button. You can edit the /usr/share/FBReader/default/toolbar.xml file and take out the network library (or any other one you don't use) if you'd prefer to see the fullscreen button. If you're using the indicator bar (rather than OS scrollbars) then you can add a small fullscreen button to there (appears in the bottom-right corner) which I find a lot better than the overlay button.

I've just uploaded 0.12.10-19 now. This only adds support for using MStarDict or QStarDict as reference dictionaries. I've only pushed this release for Fremantle as I need to look at whether these are available for Diablo (or what alternatives there are).

For MStarDict you'll need to either download my patched version from here or download the patch and compile it yourself. I'll be sending the patch on to the current maintainer, so hopefully they'll upload a patched version.

For QStarDict, basic support will work with the current version. Unfortunately it doesn't provide any support for bringing the window to the foreground though, so for that you'll need my patched version from here (or compile it yourself with this patch). I'll also be sending this patch on to the current maintainer.

EDIT: Oh, you'll also need to launch it first with the current version, as it doesn't include a DBus service file to allow the system to auto-launch it when required. The patched version does though.

Finally, the source code changes can be downloaded from here.
