You type something in this field and you get a new tab with the search results.
But WHY show it globally? What you gonna search in "Network" window?!
The point is that it's easy to search from anywhere in the app. It'll probably make more sense once the new design starts coming together more.
Sorry, but that is irrelevant. Number of "clickable elements" is meaningless per say.
True, meaningless per se. If the ratio of clickable elements to number of accessible functions is roughly 3:1 though, it's time to reduce 'clickable elements'.
* Hiding server list is wrong. This is key element of this page.
Sort of agree, but in terms of what (and that's subjective)
I usually do in that view, the server list is pretty unnecessary. One connect button would do the trick for me.
* Add/Remove/Rename/whatever you want to do with this list belong to "ED2K" section, not to bottom of page.
It needs to be in a clear relation to the server list, which it is. At least in terms of Mac standards, there may be other assumptions being made on other platforms. I agree that the server list is not however in clear relation with the ED2k part above it. That's a point I was planning to address anyway.
* What's wrong with right click? Contextual menu is one of GUI guidelines in Windows and Gnome
Nothing's wrong with it, it can still be there. There's nothing wrong with having an obvious button at the bottom of the list plus a "shortcut" right click. Personally, I strongly dislike interfaces that bury some functions exclusively in a right click menu. And if you want to be as cross-platform compliant as possible: Mac GUIs usually avoid right-click-only functions.
The main improvement I'd highlight here is this: Something that was spread across no less than 5 tabs before is now all visible and accessible at once glance, and it's even less cluttered than before. And no part has been buried* or "dumbed down", they take the same amount of clicks as before, often even less.
*) hiding of the server list open to discussion
