First of all, you would have to start from here:
This is a fork with new and extra features and modifications. It at least up to date.
If you are on windows, I can provide an installer. With this version you wouldn’t need to reinstall to further modify the web parts.
In "c:\Program Files\Quelea\server" the HTML/CSS/JS can just be modded.
That said, I could probably include features like that, but testing would be up to you. If you give good feedback would be possbile. I have added some font options for the remote already. Now that you mention it, I could do the same for the web view, it’s little effort afterall.
As for macs … I don’t care about them at the moment. I have some other projects wich might need iphone and mac builds. If i get a setup i would do this one too, but it’s not a priority.
… again, if there is a willing and able Mac used to do the builds I would include them in the releases.
