With pacman -Si you can see the info of a package, but it would be better if the info shows if the package is installed, the same goes for dependencies and optional dependencies, and in search it also would be better if we could seek the optional dependencies and see the info of the packages that are optional dependencies from the search of the parent, for example, if i do pacman -Ss dolphin it should show the current search , but if i do pacman -Ss --opt-deps it could show a tree with the parent package and then the optional dependency packages, or the dependency packages.

The reason why this would be useful is to search optional dependencies that weren't installed alongside the program and now are missing and the user doesn't know what the dependencies are, for example, sticking to dolphin, if I installed arch using the archinstall command instead of manually I will not see the optional packages at all, now, if I decided to use kde and dolphin there is a chance that the thumbnails are not available, which would lead me to think it is a problem with the dolphin package or with the OS while the real reason is that a package was not installed.

The optional packages and what they do should also be shown during updates, because that increases the chances that the user will see what they might have missed previously, I think those changes to the information shown could be a good quality of life improvement for the users that don't know as much yet, it will also be handy for users that do know, making easier to find the dependencies that they didn't installed because they didn't needed them when they installed the parent application, an example here could be when an user changes hardware and now they could use another optional dependency. I know there is a bunch of things here but I think all point to the same possible improvement (I don't think it is a problem since pacman -Si shows the info but improvements can be made)

Thank you for the great software, I am forever grateful for this amazing OS.
