We are currently using easy reader (v4.3.6) and this is not available when we upgrade to v5+.
The documentation theme gives the best range of options, but is it possible to replace the "page tree" text with button? At present, our side menu is manually created using images and we want to get away from that.
We are unable to use any theme builders or plug ins so would need the wiki markup if this is available for us to do.
