Hi Irad,
I have seen you have written this application in C# and are using .NET Framework 4.7.2 as a Windows forms application with everything in one executable.
Are you planning to upgrade to .NET to 6.0 anytime? .NET 6.0 can be used on Linux as well.
And under which licence do you provide this fantastic free software tool? Is it GPL?

Yes I know. at some point this decision will be made. but its not the right time though :)
As for plugins - VarAC is not an open source software. So what plugins/addons did you have in mind?
