Some improvements.

Hi there,

For some reason, clicking the links doesn't open them due a "Security Error"... even setting the `channel.owner` to the system principal - have you some clue why this doesn't work? In any case, that allows copying the link easily to the clipboard, which is better than typing them.

As for the skip duplicates, under latest Nightly i'm getting hundred of "Cleaning GL error: 0x500" which makes checking the log quite tedious without the option.

Cheers.
