No problem, it's been fun playing with it :)

Two more issues: http://i.imgur.com/uBpTr0m.png - somehow managed to get two links superimposed ("meteor" and "j"), and moving blocks of links took a rather long time.

That's true, I'm implementing that. Thank you for your feedback:)

Its been a week but hopefully you still see this.

I notice now what you mention but still hard to discover on your own. Perhaps implementing the Windows double click type functionality (as a setting?) would be familiar to most (as in, most people use Windows) as people are used to one click to select and a quick double click to open. But this also seems to put more emphasis on editing / the interface than the actual functionality.

For my bookmarks, I got lazy and now just use Firefox/TenFourFox/Iceweasel with a local sync server. So, I use Firefox's system, which allows for hierarchical and tag-based organization, and searching based on title. Prior to that, I used Delicious, which also had tags, and searching.

I can't speak for anyone else, but these days I use bookmarking as a contingency, in case I remember later and need or want the link to whatever. So, I'll bookmark just about anything and everything I might possibly remember, regardless of real value or intention. In the past, I used bookmarks to represent an active intention to go back and follow up on whatever, so I would carefully curate and organize my collection.

Your project seems like it would be very useful for the latter. And these days, for me, the latter comes up most often when I also intend to share the collection with others. For example, sharing a set of bookmarks to websites covering candidates or ballot issues in a local election.

Yes, sorry for the quick criticism without constructiveness. My bad.

Currently you have a color scheme based on similar brightnesses of very similar hues—green and blue are very close together on the color wheel, thus it's difficult to tell them apart and in some sense they "clash" with each other.

The grey you've chosen is also very similar in brightness, which makes the whole theme quite low contrast, and thus difficult to read.

Analogistic color schemes like this can work, but they need to be relatively high contrast so that there's enough of a difference in perceived color to make text readable and transitions more clear. And to prevent clashing, which is just generally perceived as unpleasing.

I'd go with your little memory-chip icon. Take the green off of that (#60B660) and the chip grey (#424242) and choose a contrasting accent color. You can go with a blue, but I wouldn't recommend it, and if you do I'd go with either very dark or very light used in places where it won't clash (such as maybe the top nav bar). Against the green, I'd use an orange or red or magenta in there, or just go with one main color and adjust brightnesses as needed (pretty failsafe).

Something like this would be similar to what you have, but with a better accent than blue (dark magenta) : http://www.colourlovers.com/palette/132637/Odd_but_trendy

Here's an analogistic color scheme that works due to the contrast and hue separation: http://www.colourlovers.com/palette/81885/Hymn_For_My_Soul

It's hard to explain how good color schemes are really created, other than by following the color wheel somewhat and your sense of aesthetic above all, but you can take any of these as a start for reference on what's "good." -- http://www.colourlovers.com/palettes/most-loved/past-month/m... -- Yours isn't too bad, there's just something off about it due to the low-contrast high-similarity colors used. Cheers.
