"Like" or "Save" button for considered modules

Describe the solution you'd like

I wish there is a "like" button or "saved" button for considered modules.

Additional context

@EssWhyy is taking this!

As discussed, I'll help to create a new button for each course description page to “Save Course” which adds the course to the new planner feature, under the section “Planning to take”. The planner feature will also be moved out of beta after this change (?)

Will update when I start to implement.
