I am the developer behind Open Access Helper, Wayback, TabCount & Spesensatz - all for macOS / iOSI provide all my apps free of charge on the App Store, but if you wanted to buy me a cup of tea, I'd very much appreciate it. It is totally voluntary, of course!
Thanks for the do not allow more tabs feature in Tab Count, now I can finally work more focused without the never ending tab clutter. Vielen danke!
Long searched - now found. Great, thank you very much!
Thanks for writing this extention!
