Move the TreeView to use the new "Activity Bar" API

It would be great if it were possible to have an icon on the side bar the toggles the bookmark list view!

Hi @ashmckenzie ,

I remember that in the beginning, this is how the extensions would work. But for some reason, it was changed to add a new Panel in Explorer.

Looking for news about it, I found this issue in VS Code repo, and doing a small test, I was able to move the Bookmarks panel from the Explorer
view to its own view. So, it appear it is returning 😀 .

But, I still need this other issue, which is planned only for May 2018. I see the pros and cons of both views, and I would really like to be able to choose which one to use.

Hope this helps

I would be in favor of an activity bar add vs explorer pane, largely to keep explorer more clean, and I tend to use bookmark-list over the pane

It appears (based on reactions) that maybe there is need to be able to choose between a Panel in Explorer View and an Bookmarks View (exclusive), am I right? 😄

So, let's vote?

👍 - Completely move to a new Bookmarks View
👎 - Create a setting to choose between view (wait for microsoft/vscode#48704)

I think it'd be better to make it as an option so everyone will be able to choose whichever s/he prefers. Everybody wins. 😊
