CustomReader II
I’ve released a totally new version of CustomReader, now with the Roman numeral 2 in the name. This version does away with the dependency on Diffbot and instead works by modifying Safari’s built-in Reader. It requires Safari 6, because older Safari versions do not support modification of Reader by extensions.
As a result, gone is the annoying delay that the old CustomReader forced you to endure while it fetched simplified page contents from Diffbot. Starting the reader is now instantaneous—you just activate Safari Reader in the usual way. The extension adds a new button to Reader’s HUD; clicking this button opens the settings panel.
CustomReader II still has the autoread feature from the old version, but it loses the multi-column mode. (I haven’t yet figured out how to apply multiple columns to Safari Reader in a reliable way.) If you like multi-column mode a lot, you’ll probably want to stick with the old CustomReader, which is still available here.
Please note: CustomReader II is not an auto-update from the old CustomReader. If you want to upgrade, you have to install it manually.
