[Speak To Search..]

It might be easiest to implement a sitewide google search as it already has this ability.

 

Except that would require Google to have unfettered access to your Blesta instance.. Not sure that's cool. :|

[Custom Pages]

As it stands, you can create custom pages by creating custom controllers and views. So there's some coding involved, but it's pretty painless if you know what you're doing.

 

So in theory we could create a generic page plugin to show pages in either admin/staff and client areas right?

 

Sounds like a fairly straight forward project, provided people don't want too heavy a template drive (ie. Looks and feels like the Blesta theme) and don't have too much of a requirement on multi depth pages (I hate coding for a hierarchy).

 

Edit: Sorry, re-reading the OP, it looks more like you need a products page. This is also pretty easy as a plugin but probably a separate plugin to what I just posted.
