Multi-Tab Text Editor — Work on Many Files at Once | EDTR

Open your desktop right now. How many of these do you see?

A Sticky Note with a phone number
A TextEdit window called "Untitled 4"
A Notepad full of half-written ideas
Three browser tabs you keep open "just in case"

If this sounds familiar, you have a tab problem. The good news is that the fix is also tabs — but better organized ones.

Why Single-Document Editors Fail You

Most quick-note tools open one document at a time. You make a note. You close it. You forget where you put it. Next time you need it, you make a new one. Repeat for years.

The result:

Notes scattered across Untitled 1.txt, Untitled 2.txt, Untitled 3.txt
Important ideas buried in random folders
Lost work because you cleared a sticky note
No way to compare two pieces of text side by side

A tabbed editor solves all of this. Open as many notes as you want. Switch between them with one click. Close the ones you do not need. Everything stays where it is.

How Tabs Change Your Workflow

Once you start using tabs intentionally, your editor becomes a workspace, not just a text box.

Here are a few patterns that work:

1. One Tab Per Topic

If you are working on three things at once — a project plan, a code snippet, and a meeting agenda — give each one its own tab. Switch between them instead of merging everything into one giant file.

2. A Permanent "Scratch" Tab

Keep one tab open just for throwaway thoughts. A phone number. A quote. A regex you are testing. Treat it like a digital napkin — fast in, fast out.

3. A "Today" Tab

At the start of the day, open a tab and write down what you want to get done. Close the tab when the day ends. No project management software needed.

4. Long-Lived Reference Tabs

Some tabs you never close. A list of bash aliases. A SQL query you keep tweaking. The Wi-Fi password for the office. These live as permanent tabs you can find in two seconds.

What Makes Tabs Work in EDTR

Tabs sound simple, but the details matter:

Auto-save — every keystroke is saved to your browser's LocalStorage. Closing a tab does not lose your content unless you delete it on purpose.
Persist across reloads — close the browser, reopen it tomorrow, your tabs are still there.
Per-tab language — each tab can have its own syntax highlighting (SQL in one, JavaScript in another, plain text in a third).
Per-tab filename — give your tabs real names so you can find them.
Keyboard shortcuts — ⌥T to open, ⌥W to close. No mouse required.

This turns the editor from a text box into something closer to a desktop workspace — but lighter and instant to open.

A Workflow Example

Here is a real day for a developer using EDTR with tabs:

9:00 AM — Open EDTR. The four tabs from yesterday are still there: today.md, bash-aliases.sh, query-debug.sql, notes.md.
9:15 AM — Open a new tab (⌥T) for a code review note. Paste the snippet, set language to TypeScript.
10:30 AM — Meeting starts. Open another tab. Title it team-sync.md. Switch to Markdown.
11:00 AM — Meeting ends. Close the meeting tab (⌥W).
2:00 PM — Customer asks for an export. Open SQL tab. Tweak the query. Copy. Done.
5:30 PM — Wrap up. Tabs left open: today.md is now full. Will start tomorrow's tab fresh.

No file dialogs. No "where did I save this?" moment. Just tabs.

How to Avoid Tab Overload

Tabs can become clutter if you let them. A few habits keep things sane:

Close tabs at the end of the day that have served their purpose
Name tabs clearly instead of leaving them as "Untitled"
Use the sidebar (⌘B) to see all open tabs at a glance
Pin important ones by leaving them in the same position
Group with folders when you start managing real files via the File System Access API

A clean tab bar is a clean head.

Tabs vs Files vs Windows

Some people use multiple windows. Some use one giant file with ------ separators. Some use a separate file for everything.

Tabs are a middle ground that beats both:

Faster than files — no save dialogs, no naming required up front
More organized than one big file — no scrolling to find something
Lighter than windows — switch with one click, no Alt-Tab gymnastics

Try It

Open edtr.plus and try this:

Make a tab for what you are working on right now
Make a tab for the next idea you want to remember
Keep both open

Tomorrow they will still be there.

One workspace. Many ideas. Always within reach.
