Hi All. This might be a very basic question, but I have not been able to track down an answer yet.
If I want a custom "tools" menu to show up every time I open an existing or new sheet, (1) is that possible without publishing a public add-on, and (2) how can I make it automatically visible in the sheets extensions menu (so I can enable it)?
The use case is, I want to be able to install a common menu and scripts for my own personal use, whenever I open a sheet. In the old Office world, you could create a template that effected all spreadsheets you open. Am I missing something simple? Any help appreciated.
