RosterBlur 2.0 is the one-click release.

• Presentation shield: press Alt+Shift+S (or the big button in the popup) before you share your screen. It masks every tab title and switches roster blur on everywhere, then shows an ON badge so you know you are covered. Title masking is free; roster name blur is the Pro half, and the button says so plainly.
• Free 7-day Pro trial on every install, including updates from 1.x. No account, no card. When it ends, the free tools keep working like before.
• Capture roster from the page (Pro): open your gradebook or class list, click Capture in the popup, then click the list. RosterBlur extracts the student names, shows a preview, and saves them as a roster. No more typing names in.
• Pro keys now activate with one click on the purchase confirmation page. Pasting still works too.
• New Pro options: natural fictional names instead of "Student 1" labels, blur student photos, blur grade cells, and a never-blur list for names that should stay visible (like yours).
• The popup gained quick roster toggles and a count of names hidden this week.
• Site licenses for departments and school buildings, one key for the whole team.
• Fixed a bug where settings changes arriving in the same instant could be dropped.

Still zero network requests: rosters, settings, and your license key never leave this browser.
