1.1.0

• Improved: Made scrolling notes into view on tab header click more reliable.
• Improved: Don't scroll to canvas header after clicking tab header; allows full view of canvas note within window.
• Improved: Arrow navigation between notes is more reliable, especially for pdfs and html notes.
• Added: Use left/right arrow keys to scroll html notes up and down or to navigate from page to page in pdfs. (Space bar still works for default scrolling.)
