Automatically open sidebar when activating extension

When I click the browser extension icon to activate it on a page, this collapsed sidebar appears:


I then have to click the left chevron to expand the sidebar.

I appreciate that this design was probably reached out of an understandable and often very valid desire to avoid encroaching on the web page's screen real estate. However, when browsing on a large monitor with a wide browser window, there is plenty of space available, and it would be preferable to avoid the need for this extra click on every website where the user wants to see the full list of annotations.

So I suggest that this should be a configuration option which each user can set individually in their browser extension.

Another improvement would be to provide the ability to configure a keyboard shortcut for expanding/collapsing the sidebar, although I think this should be provided in addition to the option to automatically expand it, not as a replacement for that functionality.
