Yes...
Situation Update: LH_TS3 was fully functional for A19 when A19 was meant to include a major rewrite to the way plugins worked, i.e. Plugin API6. But then API6 slid back to being unstable and A19 was released with the existing Plugin API5 - which LH_TS3 didn't support...
Anyway, I've not been happy knowing that all my hard work was tied to API6 when API6 still isn't released, so one of the things I've been doing on my holiday (while my wife and my in-laws all talk in a language I barely understand) has been to rewrite LH_TS3 to be API5 compatible. This is now done and is working great so it will be included in the next LCDHost update (which will add a couple of key features I need to the current Plugin API5).
As for then that will be, well, the only certainty there is "before the current version expires" and "not before I get back from holiday" as without internet access I couldn't deal with any bug reports if people find something horrible that I've missed in testing.
(P.S. Note that the plugin is only compatible with TS3 v3.0.1 and up so make sure you've updated from 3.0.0.)
