The idea is that you could organise your selection of bookmarks, like you can in a selected folder and sub-folder of your operating system. EX List (music) in différents folders (classic, rock, ...)

Annotation on PDF document

The only feature that delicious has and that I regret Diigo hasn't

- Our information is OURS not on your servers
- Content is indexed and searchable from Mac Spotlight or Windows Search.
- Annotations are available offline

It would be nice to be able to search our bookmarks directly through the extension (so as in the Delicious extension in Firefox).

Add ability to color-code tags, similar to gmail's labels.

This might not be useful for all, and it's probably a "maybe later" feature. But Gmail style filters would be really useful.

Eg:

If tagged A and B but not C, add to list L1 and submit to group G3
If tagged F and unread, add to list L3.
If tagged G and H and read, add to list L4, add tags T1 and T2, submit to Twitter and Submit to blog.

Diigo is a great tool for collecting information, in order to be more useful in the academia, it should offer creation of bibliography and citations according to accepted formatting rules used in journals and publications. Tools that already have these features and somewhat overlap with Diigo are for instance Mendeley, Endnote Web or NoodleBib.

I have multiple related tags that I would like to relate under a common tag.
something similar to gmail folders:
X / bla
X / bla2
Y / bla3
this way would be easier to categorize items.

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.

Often I find myself adding tags several times but each time in a different language. Ex. I add an English tag and also the same tag but then in Dutch. As a result links get cluttered with lots of tags. Wouldn't it be an idea to have the possibility to add synonyms (translations) to 1 tag so that adding 1 of them immediately makes the link searchable via the related synonyms too?
Just a wild idea that popped up :-)

I am a member of several similar groups. When I find a site that could be helpful for more than one, I have to bookmark it multiple times in order to share it with each group.

All tagged items could be linked together through semantic relationships such as: "evidence for", "argument against", "relies on", etc. This could potentially culminate in a concept map mode—displaying the web of connections around particular tagged items.

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

As more and more people move to the cloud to do work, and store their data, it would be incredibly useful if we could highlight pdf documents we read online.

Thank you :)

Create a quicker way to access bookmarks in chrome, maybe using the extension.

The only way this can be currently done is by going to the diigo site, which is quite clumsy.

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.
