Yes, that is good, though there seems to be a bug in version 0.18 which means that when you click through the Subscribe button doesn’t show up (just the word “Subscribe” where it should be), so you end up having to search for the community anyway to subscribe. Once that bug is fixed though it will be nice and convenient.

Edit: I found another workaround: If when you first click through to the community the Subscribe button isn’t shown (for me it just shows the word “Subscribe” but it’s not a button), then change the “Hot/Active/New/etc.” dropdown to a different value. This refreshes the page and the Subscribe button appears.
