Memberships2 and Appointments+ buttons

I have been using some of your plugins for almost a year, and deciding on Memerbships2 and appointments+... however, now that I've installed them and tested I noticed that the buttons in general were not given a lot of love :slight_smile: They really look bad and don't fit on mobile devices (who designed this?) Here are the primary buttons I need help to be LIVE with my site:
1) memberships2: "signup" button and others (they are ridiculously small and unfriendly) how can I change them
2) Appointments+: "Please click here to confirm this appointment" / the longest button text ever created... how can I change and customize these, please.
3) The language used on these buttons and forms - where can they be customized??

Thank you in advance for your time.
