"I dislike the fact that you have to complete reload your page for the tiniest change."

100% agree, and technologies like XML island (DHTML category) etc is aimed to address this issue. At this point, it seems like javaScript/DHTML is the most common way if you wish to address this.

Add a little bit for people who is not familiar with DHTML: it is not another standard similar to HTML or XHTML, but rather a very vague concept to group any technology that make web page "dynamic".
