More/Less 3.0.0
by Luli
If you write lengthy work emails, then this one's for you! Structure your emails with More/Less into a crisp summary, expandable side notes, and rabbit-hole appendices, handing over the power to the reader to either glance or dive deep.
About this Add-on
Professional communication often asks readers to absorb too much information at once. Keep an email short, and important context can disappear. Include everything, and the message becomes a wall of text where decisions, explanations and essential details compete for attention. More/Less offers another way.
Responding to information overload and reader's fatigue, More/Less offers a different way to structure an email. Based on the principle of progressive disclosure into your email composer, More/Less organizes information into clear levels of detail, allowing readers to understand the essential message first and explore additional information whenever they need it.
The result is a more considerate way to communicate: less visual overload, clearer priorities and greater control over how information is consumed.
HOW IT WORKS
01. The essential message.
Keep the main communication concise and immediately accessible. Present the purpose, key takeaways and requested actions without burying them in supporting explanations.
02. Discover More.
Organize additional information into dedicated sections. Explanations, background, definitions, rationale and related discussions remain available without overwhelming the primary message.
03. Appendices & Attachments Keep supporting material organized below the signature. References, technical notes, links, file descriptions and other details have their own place, making them easier to locate when needed.
DESIGNED AROUND THE READER
A recipient can scan the essential message in seconds, open the sections relevant to their needs, or explore the full depth of the communication. This makes More/Less particularly useful for:
- Busy professionals
- Project updates and progress reports
- Technical explanations and specifications
- Proposals and business correspondence
- Client communications and recommendations
- Complex decisions requiring supporting rationale
- Emails with multiple topics, references or attachments
AN ADAPTABLE EMAIL ARCHITECTURE
Email apps do not all support the same technologies. More/Less accounts for these differences through a adaptive dual-path layout (a fancy way of saying that it adapts the delivery layout). Where supported, information is presented in interactive, expandable sections. In restrictive email clients, including desktop Outlook configurations that block interactive scripts, the content adapts to a structured, readable two-column layout. The underlying information remains organized and accessible, even when interactive features are unavailable.
LOCAL-FIRST. PRIVATE BY DESIGN.
More/Less is a local composition tool.
No data collection: No telemetry, tracking pixels or analytics.
No cloud dependency: Drafts, sender profiles and messages remain within your Thunderbird environment.
No external accounts: No additional cloud service or account is required.
Self-contained output: Your emails are generated as HTML, ready to be sent through your usual email workflow.
A LITTLE MORE CLARITY. A LOT LESS CLUTTER.
More/Less gives you the freedom to communicate with depth while respecting your reader's time and attention. Write the complete message, just structure it better!
