Make the Diigo Sidebar 2 -tiered so that I can browse my Tags in a top window and see the links for a tag in the bottom window and acces a link directly from there . . . just like in delicious.

If favicons of the sites that we are bookmarking can be used in some places that would be nice/functional. In a long list of bookmarks it is easier to find the link you are looking for

It would be great feature, if Diigo offers a Drop Down menu of all the Tags currently in Use. I think at the moment it only offers the Auto Complete option for the Tags.

I will allow better use of all the existing tags without creating new ones everytime.

I find it painfully time consuming to tag my annotations whether from the toolbar or the website. It would help if a dialog box would pop up every time I highlight something, letting me tag it. I realize that this would bug some people so you could create a settings option to turn it off, or make it 'once per webpage' instead of every time. It's more efficient than having to go and tag things after the fact like I'm doing today with almost a hundred highlighted pages that I never tagged.

Similar to Delicious sidebar, you should be able to right-click (context click) a bookmark in the sidebar and choose 'properties' (or similar) and edit the title, link address, notes etc.

Use Zotero references and upload them to Diigo via synchronization with comments and tags and attachements (PDFs, Images, links, etc)

I little known feature of delicious are "shortcuts" (also known as "keyword"). Basically, you can make up a quick alias like "docs" for google docs, or "ymail" for yahoo mail, etc.

Your favorite sites are just a phrase away. :-)

I'm an extremely visual person and need thumbnails to tell my bookmarks apart. Delicious does this by adding the web icon. Please do the same. It would be an immense help!

I would like to access My Library with one click of a button. Right now I have to go through a pull down menu

Diigo is doing fine but it still needs lacks implementation. One striking side is that it misses search bookmarks directly from Firefox awesome bar (address bar). Delicious does have this great feature that is very handy to reach my bookmarks.

make Diigolet work like Instapaper's Read Later bookmarklet. Diigolet doesn't work with NoScript on Firefox if the domain name currently visited has JavaScript disabled

On Delicious I loved their tag tree, where I could "expand" the entered tag to see which tags can I use to narrow the search. So even when I did not remember how exactly I tagged the item, I could enter some generic tag and see which other tags I used to distinguish it.

Would be nice to have sth similar on Diigo.

It would suffice if - after I entered the first tag in the filter - Diigo offered list or cloud of related tags (those tags which are present on some pages bookmarked with the first tag).

so if I have 7 links with a certain tag, I can open 7 tabs - one for each link - with just one click...

how do i delete ALL bookmarks at once. i cant find it on safari IE chrome firefox any toolbar any extension. this is impossibly difficult.

Include Google Plus Circles as possible recipients of sent bookmarks

In a large page, positioning sticky notes is difficault. It is good if page is scrolled as sticky note icon is dragged out of the page area.
