The new HTML5 Glog editor is now being rolled out to all newly registered accounts.
You may be aware that the previous editor was flash based and is now being phased out by providers of web browsers (Google with Chrome being one example). It became apparent over time that flash had inherent issues and it will not be possible to switch users back to that editor. HTML5 (the tech of the new editor) has various benefits moving forward including much faster rendering speeds.
The search feature in the editor is available via 'Add' > 'Web picker' - see the image below.
