Hmm, random thought I just had while I was working on one of my college project, that is, I'm in charge of coding a search module for a website, which integrates some tagging features.
I remember some years ago, I had suggested changing the way tag are handled on Shuu, mostly, using quotation marks as delimiter. I have always found find them rather inconvenient, because missing one quote mark implies error. Problem might be solved with auto complete, but I find it faster to just type whole theme tag because the arrow down key is just too far from the normal typing position to pick them in the autosuggestion list.
So as I was working on my project, I did have to implement some Javascript for tags, and that's where I found this:
https://github.com/chrisleishman/tag-itAs you can see on the demo ( scroll a bit to see them, and click on example.html to test ), it wraps each tag in a bubble ( aka like a lot of other website ). To do that, you just press enter or tab ( double tab to change input focus ) after completely writing the tag or you select from the drop down list. Original version allowed anything to be wrapped in bubble, but this fork has an option to lock tag to the suggested list. I also edited the Javascript to allow the bubble wrapping when you type the tag entirely ( perhaps I will change this behaviour to "pick the first element in the autosuggestion list" ) (Perhaps I should provide my own fork )
So, I'm just wondering if people would prefer such system. Better say, I have little to no say in what gets implemented on shuu.
