Plainly 1.6.0 adds:

• Paste sites — quickly enable Plainly on commonly used paste and coded-list sites.
• A preview of the sites that will be added before access is requested.
• Nested decoding — layered coded text can now be decoded in one operation.
• A more compact and straightforward menu.
• Improved handling of browser permission prompts.
• Reliability and Firefox compatibility improvements.

Plainly performs decoding locally in the browser and does not collect or transmit user data.
