These are nice fixes, @LauraH is right all these little things can really add up to a much improved impression of the app. My particular setup avoided most of the scrollbar hassles, but this has improved the look of my Mailbird integration nicely.
Being able to resize the Overview Drawer might make it marginally more useful, but my main complaint is that it does double duty as an inexplicably-ubiquitous Document Manager. I’d really rather see it tweaked to be a true “Overview” of the Pane’s currently-selected Document(s). Why do I need the ability to inspect and manage ALL my documents right from the sidebar of every single pane, in every single board? This is the biggest reason I never leave the Drawer open. The current width, which lets me get down maybe 4 or 5 tiers, is enough to do quick high-level navigation, and I would love to use it that way – but I can never “find where I am” in the Overview fast enough with all my other docs cluttering it – not helped by the scroll always resetting to top.
I think Document Management should be a separate place, either in Settings or from a button in the Board Bar. The Overview drawer should just be a Pane Overview. It’s attached to a Pane, after all –why is it “about” anything but that Pane?
