Compare with Apple's web apps, which strike the best balance between reasonable customization and simplicity (i.e. I don't need any of the profile configurations and what not, I just want a working app that will work always; that will adjust to my system and blend in nicely with it, from showing the right (shape of the) icon to behavior).
Right now some web apps, after being closed, don't work. I have to relaunch them. And not all pages can be made to web apps.
