QR Tour
A mobile bilingual station tour with dedicated content management, accessible interaction and clear navigation between physical place and digital content.
DESIGN ROOTED IN CRAFT AND CODE
Well designed. Clearly built.
I am Christian Elstner – master stonemason, designer and web developer. I create websites and digital tools that fit the people, the business and the everyday work around them.
SELECTED WORK
Independent projects, different worlds.
I do not begin with a finished visual style. The task comes first: what should become easier, who will use it and what must hold up in real work?
Product design · Web app
Scribentia
A comprehensive writing environment for characters, worlds, plot, manuscript and book production – designed for long projects instead of short prompts.
Add-on · Interface
Quick Workflow Bar
Recurring emails directly in Thunderbird’s compose window – with personal workflow buttons, 48 icons, custom colours and an optional character row.
Book project · Illustration · Interactive website
The Cloch
and the Great Winter Heist
An illustrated Irish Christmas story in verse, with its own book website, a reading sample and a playful winter world. Snow gathers along the screen, a curious wren follows your movements, and a magical sack clears it all away.
WHAT I DO
From the first sketch to the working tool.
Websites & web apps
Individually designed and carefully built – from a focused project site to an application with its own content management.
Interface & interaction
I structure complex functions so people understand what they can do and what happens next without taking detours.
Visual design
Type, colour, imagery and grids are developed for the task and the project’s character instead of being added as decoration.
Focused tools
When existing software does not fit the workflow, I build a focused tool for that particular day-to-day job.

New in version 2.4.0
Start faster with 40 templates in seven languages — included in Free and Pro. Plus a clearer toolbar and new text formatting.
Choose a template and get started.
Greetings, closings, business phrases and complete emails: choose a language, read the preview and adopt individual templates. In Free, selected texts use up to three active slots; fill in your details when adopting a template.
More visible, easier to find.
Buttons wrap automatically across up to three rows and can be expanded further. Reorder workflows by drag and drop. Restore the workflow collection from before the last save when needed.
Highlight what matters.
Pro adds a highlighter to the rich-text editor: select text and choose its background color. A visible A with a color bar controls the text color. Pro can also adopt all seven linked catalog languages.

Install the add-on
Install the free Quick Workflow Bar from the Thunderbird add-on directory or the XPI file.
Buy a licence
Purchase Pro through Lemon Squeezy. Your order confirmation includes your personal licence key.
Activate in Thunderbird
Open the add-on settings → “Pro & data” and activate the key. Pro can then be used offline.
Before you buy.
Why is the price in US dollars?
The purchase is processed in USD by Lemon Squeezy, so we also show the price in USD. In another account currency, the amount may differ due to exchange rates and conversion fees.
Do I need a different extension for Pro?
No. Free and Pro are the same extension. The licence key unlocks the additional features. An existing valid Pro licence does not require a new purchase to update to version 2.4.0.
Which languages are supported?
The interface follows Thunderbird: German or English, with English as fallback. All 40 standard templates are available in Free too, in German, English, French, Spanish, Italian, Dutch and Polish. Pro links multiple variants. Your own text is not automatically translated.
How do the two activations work?
You can activate the licence on up to two personal installations. Activation requires an internet connection; the local certificate is then checked offline. Before switching devices, deactivate an installation you no longer need. The licence covers the purchased major version.
How do I enable the character and emoji row?
The row is initially disabled. Open the add-on settings → “Characters & emoji”, enable “Show favourites row”, then save. Choose from the suggestions or add your own characters. Only Unicode text is inserted; an emoji may look different on the recipient’s system.

Message content stays local.
Your templates, message text, recipients and attachments stay locally in the Thunderbird add-on. Pro activation and deactivation connect to the licensing service; no email content is transmitted in the process.
ABOUT
Design rooted in craft, technology and curiosity.
I am Christian Elstner, a master stonemason and stone sculptor, designer and web developer. My work has long moved between material-aware design, digital interfaces and independent software.
The common denominator is not one visual style but a way of working: understand first, then structure, design and test until the result works in real use.
HAVE A PROJECT IN MIND?
Tell me where things are getting stuck.
You do not need a perfect specification. A few honest sentences about the project and the actual problem are enough to start.
