I really would like to use Chrome/Chromium, but what I am missing hardly is a bookmark panel, which is shown all the time, like in Firefox and in most other browsers. By "bookmark panel" I mean the tree that lists all bookmarks and that is displayed on the left side (what you get when you press CTRL + B in Firefox, Firefox calls it a "Sidebar").
I couldn't find a extension for that. Does some has an idea?
I don't think Google would consider that; part of Chrome's appeal is the
minimalistic interface. Many users of other browsers have complained as to
how bulky sidebars can be, so I doubt Google will add them.
But anyway, you could check a non-ideal way to make something sidebar-like.
I was looking for the exact same thing then came across CoolNovo which is based on Chrome and has a sidebar.
I just installed it, set up syncing with my Google account and it's syncing all my extensions and bookmarks right now. It basically seems the same as Chrome on first look which is great. I'm using the portable version at the moment to try it out. Check the screenshot for how the sidebar looks with Bookmarks.
It doesn't fix the problem in Chrome, but it's a good alternative so far.
(Use Open-as-Popup or similar extension if you want, to hide all toolbars and tabbar)
Tile windows or manually resize them to be side-by-side
Or you can alternatively make bookmark window on-top/transparent/easily brought up (with win+#/taskbar icon click in Win7 or something similar to gain focus of it)
If you want just some means to manage "sessions" of pages that should be easily accessible but not in the memory, you can use one of extensions that allow you to manage tabs in sidebar fashion (be sure to read detailed extension description)
