Ok, after some research I think I just fount the best (ehm, the most round?) HTML/Web developing editor around. Of course that if we discard WYSIWYG editors, which I personally abhor. Thank you for your help.
This is, however, the result of my research (I thought you might be interested on my conclusions):
(1) SkEdit, thanx to Pengu for his advice. It is neat (ehm, round?), easy to use, very complete, multi-language and features a kindda tabbed navigational system (ok, it is not through real tabs, but it is ok after all). The only drawback is that it is not free, but it is worth the $20 it costs.
(2) Smultron, a GPL editor, is possible the best I've found in the free editors "competition". Not as complete as SkEdit, it resembles a bit TacoEditor but it is more... round (aaargh, what the hell, well rounded). Not as complete as jEdit but farily more intuitive.
(3) Web Design 2 is a program that reminds me of many PC Web development counterparts. However, the program looks unfinished (although it is not, which means that this program is not very... ehm, round).
(4) BBEdit (full) is good, but falls behind many others nowadays. They MUST introduce a project management or, at least, tabbed browsing to make web developing an easy, agile task.
(5) Mostly, the rest suck. What do you find at SubEthaEdit apart from being able to edit a document within a group?. Did I miss anything?
