The menu Tools → Options → LibreOffice Math → Settings is only available if Math is launched as standalone application: if you insert a Math object in Writer and then go to Tools → Options, the LibreOffice Math section is not present. Math is best used as an OLE object inside other documents and not as a standalone app, so being able to access its settings when used as an OLE object is very important. That menu offers several options useful for most users, such as the scale factor in the editor, deactivate the "visual edition" enabled by default in 24.2, etc.
Other apps such as Writer and Calc also have their own entries available only when the application is running. TBH I don't know why we hide the options for apps that are not running. I would show them all, all the time. LibreOffice is an office suite, and Tools - Options should allow to configure the entire office suite, regardless of which application is running. Is there any technical issue that prevents showing all options when an application is not running?

Also noticed that the associated expert config stanza 'InlineEditEnable' provided when visual mode was "graduated" from experimental [1] is not quite right. Despite the noted inability to reach the Math module specific options during OLE edit, the expert config should work from any module via Tools -> Options -> Open Expert Configuration. The stanza gets recorded from expert config to user profile registrymodifications.xcu, but it does not override the value set apparently *only* from the Tools -> Options -> Math -> Settings dialog. Seems like the registry value should follow along with both the settings panel and the expert config stanza. =-ref-= https://gerrit.libreoffice.org/c/core/+/156486
