Hallo.
First at all, congrats for this really light browser.
I was looking for a lighter alternative to firefox with gecko.
Now.
I have some usability-suggestions which i use with firefox all the time and is not on kmeleon.
I want to use Flashget or other download managers with it. In firefox it is provided by flashgot extension.
The bookmarks are very hard to use. Pageicon is not stored and becouse of that all the icons are the same.
There is not "add here" button on each folder, so ones have to add and then move it.
There is no right-click menu on bookmarks to open it in a new tab.
Also, tight-click menu for tabs the first option is to create a new, and looking in the middle is close tab together with close all. One mistake and you close all. I think that it has to be first.
Ctrl+click opens a new tab but doesn't keep the focus on the current page. I usually open in a new tab multiple links of one page.
Finally, the feature of firefox fot rss in the bookmarks is really good for me. I use it a lot.
Well, those are just suggestion. I hope to see some a newer releases.
cheers
