Hi Rob, as I wrote several times - we provide support on tickets and skype for all customers with paid subscription. We always try to respond on all tickets, just demo users have lower priority.
Customers with free demo version can write the topic on forum and we try to answer there, yes it can take long time, but probably we haven't seen this particular message, I don't know why it was not answered for 2 months, sorry for that.
Regarding new features and release - we are trying our best to launch 1.3 version soon. Yes it was planned to launch 2 months ago, but we have plenty of custom development and things like Xero and Quickbooks integration took much more time that we planned.
For people who cannot wait and need to use latest features, there is always :
apt-get install splynx-dev
that installs the latest development pre-release version of Splynx
