Currently, to enable the Development Tools the user needs to use the Standard Menubar, by going to Tools > Development Tools. I would like to suggest adding a Toggle button to the Tabbed Interface (under the Tools tab), to make it easier to enable/disable Development Tools without having to resort to the Standard Menu.

Indeed, i don't see it in Version: 7.4.0.0.alpha0+ / LibreOffice Community Build ID: 0723b41bed9bb4ad50d2993744a60177966d1a21 CPU threads: 8; OS: Linux 5.10; UI render: default; VCL: gtk3 Locale: es-ES (es_ES.UTF-8); UI: en-US Calc: threaded
It is in the Tools menu (on the far right), not in the ribbon itself. Closing since OP himself wrote the fix and is happy with the result.
