Something which worked well for me so thought I’d share. If you have lots of identical buttons (I had lots saying ‘Post an event’) then you can set up an option set so that when you change the text in the option set, all the buttons update in one go. This is useful if you are unsure/change the button text often. Same applies for navigation link text.
I use this a lot for navigation links.
You can also consider the use of ‘app text’ for the buttons.
