Dia 1.18.1 for macOS

v1.18.1 makes it easier to shape your workspace around the way you work. From more intentional Tab Groups to better window restoration and faster startup on lower-spec machines, this release focuses on keeping your setup organized, reliable, and responsive. Here's what's new:

• Tab Groups are now auto-pinned. When you create a new Tab Group, it's automatically moved to your Pinned section. If you're grouping tabs intentionally, they stay anchored where you expect them — reducing the need to reorganize as your tab list grows.
• Reopen closed windows in one click. You can now restore an entire closed window from the File menu, including all of its tabs and Tab Groups. No digging through History or reopening tabs one by one — your setup comes back the way you left it.
• A cleaner, more intentional Bookmarks Bar. The Bookmarks Bar now only shows Tab Groups you've explicitly closed and moved there, and only if they aren't open in another window. What you see reflects your intent, helping your workspace stay tidy.
• Improved tab spacing and readability. We corrected a tab truncation issue in the Tab Strip when Tab Groups are present, improving spacing and label clarity so your layout feels more predictable and easier to scan.
• Close Tab Groups directly from the top bar. You can now close expanded groups without shifting your focus to the sidebar, making group management feel more natural wherever you're working.
• Scroll to background tabs automatically. When Command-clicking a link while focused on a Favorite, the sidebar now scrolls to reveal the newly opened background tab — so new work doesn't get lost offscreen.
• Copy multiple tab URLs at once. When multiple tabs are selected, you can now copy all of their URLs in one action from the context menu — helpful when sharing research or moving work between tools.
• Import Chrome Tab Groups as Bookmarks. Bringing over your setup from Chrome is now smoother, with support for importing Tab Groups directly as bookmarks.
• Dark incognito windows. Incognito windows now launch in dark mode by default, making it easier to distinguish private browsing from the rest of your workspace when switching contexts.
• Faster startup on lower-spec machines. Over time, large favicon caches could slow startup on systems with limited memory or slower storage. We now cap the cache at 1,000 entries — more than enough for everyday use — keeping launch times fast after the first run.
