In the SO main page you can add/remove your own 'Interesting Tags' and 'Ignored Tags'. Well, I navigate fairly often by the 'Interesting Tags' to find questions of interest. I've arranged the 'Interesting Tags' according a specific order so that I can quickly find them. But very sometimes (often during page load while the
(x) delete icons are still not appeared) I accidently click at the delete icon. There goes the tag.
True, I could add the tag again and then remove and re-add all other tags so that the deleted one reappears at the place where it belongs (because I can't seem to find a way to arrange them). I have them a bit grouped and ordered on the actual interest and subject. For example, server-side stuff like Java/JSF/JSP/JSTL and so on the top, the tools like Tomcat and Eclipse in the middle and then the client side stuff like HTML/CSS/jQuery on the bottom. All just for the easy and intuitive navigation.
Shouldn't the delete icon better to be supplied with a
return confirm('Are you sure?') in its
click event or so? It's also much better for UX. The 'delete comment' button also has a confirm dialog.
Update: as it still annoys me and a confirmation dialog is likely not going to come, I created a userstyle. One may find it useful as well: http://userstyles.org/styles/24524
