@tags — tag people and contexts in your tasks

Type @ inside a task to tag a person or any context — e.g. talk to @matyas, then send docs.

• Autocomplete — typing @ opens a filtered dropdown of tags you already use. Tab/Shift+Tab or ↑/↓ to move the selection, Enter to insert. The tag lands with the cursor right after it (no trailing space), so @matyas, flows naturally.
• Sidebar entries — every tag with open tasks appears in the left rail below your lists, with a live incomplete count, sorted by how many open tasks reference it. Click one to see all its tasks.
• Tag search — a search starting with @ matches by tag. Partial and word-start matches work: @olch finds @piotrOlchawa.
• Readable display — @piotrOlchawa shows as "@piotr Olchawa" in the rail and capitalized inline. Accented letters fold to ASCII on save and casing is unified, so a person is one tag no matter how you type them.
• Drag onto a tag in the rail to add it to a task.

Tags live inline in your todo.txt using the standard @context convention, so they stay compatible with other todo.txt tools.
