This stuff is great and usefull, but...

Currently settings is not working within All-In-One Sidebar.
Temp solution: open 'about:addons' from url bar and do settings from there.

The homepage url on settings page is pointed to the 'old version' original extension.

Drag-and-drop search is not work in some(?) site (eg.: addons.mozila.org). :) Currently I found this one only.

Visibled zones contains icons and labels but labels has 'technical' label eg.: 'search-google', "search-custom-1', etc.

Labels and icons are not customizable.

Only three custom search engine available.

The extension has own fix search-engine list, not use my search engines (confgured in firefox main settings).

I think if you can resolve using firefox serach engines, then would be forget label/icon customization, and custom search engine configuration.

I wait the next releases!
Thank you!

Oh, I miss Web Search Pro so much! And I didn't imagine you were Captain Caveman, good to know you're back in the scene. I miss so much the "group search" from WSPro, made my medicine online quoting so quick! ;-)
OK, about DDZ Revived: thanks!! Worked like a charm so far, will keep on updating here if anything changes, but running as intended.
What I missed (but it's fully usable, thanks!): maybe updating search engines here and there would be cool, as we add and remove them along the time. This would avoid inserting custom URLs since, without WSPro I now do my searches mostly from the awesome bar (and created keyworded bookmarks to make it easier).
Also, maybe it'd be cool to have one's keyworded bookmarks on the list for adding them.
The old visual (translucent) was cool... ok, just GUI details. :-)

Thanks man! Found you again through Native Client (required by YT Downloader-WE), thanks for both!
