I'm quite decided for the HomePageEmbedded branch and now it's the right 
moment to speak about.
I'm aware there are some "loading" problems about. But it's not that bad. And 
we gain a lot of semplicity and robustness compared to the HomePage branch.
Loading and snapping webpages is very slower than rendering the pages.

Again, we have the predicted trade-off. 
Showing common sites, you need just one time to grab images (very slow, about 
20 seconds) and then viewing the homepage is "superfaster".
With the HomePageEmbedded branch, you load every time from 1 to 10 sites (the 
homepage + 0 to 9 previews). It tooks.. don't know how much time. The 
important thing is that the homepage is just ready and we don't need 
mechanisms to retrieve images every time user change sites.

So, what's best?

I tried in my local branch a simple implementation of that. I used just 2 
classes and about 100 LOC to show a pager and a calendar in rekonq homepage.
And I'm thinking now (while writing..) that we could for example load a 
plasmoid (rss?) into a webview. And load it trough the qt/plugin mechanism.. 

We are browsers.. :)
