Hi there,
today it happened twice to me, that I uploaded a wallpaper and added tags to it. While clicking on a tag suggestion to add it I accidentally clicked on an already added tag and the page automatically changed to the certain tag archive.
Especially on the page where you add tags and everything, it would be great if there would be some kind of notice, warning or dialogue if you (or the site) try to leave the page. It's also very easy to click on a tag, if you try to delete it.
There's always target="_blank" for links, but that wouldn't be w3 valid. Just saying...
It's just a request. You still can call me an idiot and tell me to keep an eye on where I click. ;)
Take care!
