The potential is/was big but in my 1st test I already ran into Major limitations.

There is no real control over placement and or sizing of the box. So, a site menu at the top which drops down, which covers a high percentage of site, will have obscured menu options ... the users can't see or select them. Checked with support and this is as it is.

A tooltip can appear after a set time, but can't disappear after (another) set time. The solution from support was 'the user can close the box' but I guess they don't know how users are impatient and Don't want to have to do extra things/clicks.

We'll test a bit more but these 2 things are show-stopper enough for a likely refund regrettably. What a shame for so much potential.
