kyrios In Solus by default only the libreoffice components that most people will need are installed by default.
I think that is a good choice. Every distro I've looked at over the last year seems to do that as well. Few ordinary desktop users need Base and next to none need Math.
kyrios like for most applications in Windows, if you select custom instead of typical during the installation it will allow you to select what you want to install instead of installing everything.
That's true -- LibreOffice custom installation in Windows allows users to select or deselect program features, languages, dictionaries and lots of other stuff -- but Windows custom installation doesn't allow users to pick and choose which applications (Base, Calc, Draw, Impress, Math, Writer) to install.
I remember that OpenOffice used to offer that option, and maybe the earliest versions of LibreOffice did, but at this point LibreOffice installation doesn't. With LibreOffice, it is all or nothing.
To make sure that I wasn't relying on my aging and sometimes unreliable memory, I uninstalled LO 7.1.03 and installed LO 7.2.5 (LibreOffice_7.2.5_Win_x64.msi) using the custom setting:
Custom installation did not offer choice of applications, and when the Windows installation was done, all six LibreOffice applications were installed:
I'm not sure why Windows installation is all or nothing, but that's the way it seems to be. That's fine with me, as is the decision by the Solus team and the teams responsible for other distros to include only Calc, Draw, Impress and Writer in the default installation.
