ecto 2.1 is now available for download here. The major features added to this update are Amazon search and additional settings for Upload Preset. This version also includes a number of important bug fixes, including a fix for the "Registration Error" issue. Please read the history.txt file for details.
You can now search Amazon from within ecto to add item details to your post, and you can customise how the item looks in your post using the template feature.
Thumbnail Upload Preset
Upload Preset now includes thumbnail settings. When saving a preset, ecto remembers the thumbnail's width and automatically calculate the thumbnail height the preset is applied.
