Hi PCNetSpecs,
Glad to hear PM9 on the way......

When people will get this New PM9 release to download? Is it based on 17.04 or 18.04?
I request you please do something to resolve two bugs which is given below:-
1. To Disable and Set a Delay on a Laptop's Touchpad While Typing
2. Lot of new laptop facing issue with right click issue on Touch pad in 16.04 (PM8)
Few suggestion you may want to consider
I understand that Peppermint is minimal Distro and it is great that way. But Are you Planning to improve Peppermint repository to add more popular and most demanded software and utilities which can't be Pre-install in Distro. So user will not require to add Third party or unknown PPA to install software or other one or two click mechanism to do the same.
Easy way to mount SMB share (Windows Network Share folder) with new OS like windows 2012 or Windows 7 onward. Because Microsoft disable SMBv1 or SMBv2 by default in their OS. So Nemo Server connect and gigolo software application stop working with Windows shares or give issues and FSTAB method syntax change with every release. And its stop working.
There should be something in Peppermint control Panel to manage and install fonts in peppermint.
It is just suggestion if it is fit along with you goals then do something otherwise ignore it.
Regards,
Rajeev Gautam
