Hi!
I discovered Slimjet yesterday and since then I have been testing it. So far it works very well. Only sometimes I have noticed small lags on some pages, but overall everything works well. I hope that future releases will improve it even further.
There is one thing that I would like you to implement: bookmark bar auto-hide. This feature is standard in one browser that I used to use. This option makes browser window feels bigger. Besides that, bookmark bar is not necessary to be present there all the time.
I hope that this feature would be interesting to you and that it will be implemented in Slimjet.
