I am looking for a way to handle block include/exclude more easily. Is there a way to have an autofill/autocomplete function in the block include/exclude field? It would be perfect if this could be done in the same way as CKeditor Link handles autocomplete on internal links.

This plugin allows you to accept Bitcoins and Litecoins with your Drupal Ubercart plugin using BTCMerch.com payment processing system.

I see from Google AdSense SSL support page that they now support secure ad serving through SSL on HTTPS web pages. A slight code change is required. Will the Drupal AdSense Module be updated to allow this change for those drupal sites using https pages? Will the AdSense Module be updated soon? This would avoid the mix content message to browser users when accessing https drupal pages containing Google Adsense ads.
