I`ve been using the beta for few days now - sometimes it crashes with many tabs opened, but as for beta - it does work great. I must say that i like the new tabs very much
Well, the older style was nice to - but i enjoy the change. Rogue, i think you`ll get used to those tabs
What i miss in Safari 4 is - stop/reload button, and a button for Top Sites...i know most ppl would say that using Cmd+Opt+1 is easier - but im just used to move my mouse to the left side of address bar and click the button...well, i surely wont get used to using this keyboard shortcut
What i dont like in the GUI is...ok, i know it`s stupid - add to favourites button sticked to the addres bar...it hurts my taste :P would rather move it to the left.
About the browser, hmm, it sometimes miss few things on the sites using a lot of java/flash, it`s working faster, i like the top sites function and the animatios, and i hate the fact that loading progress has disappeared from the addres bar. Think that`s all
