OK,
so I created this program as a simple program with no template.
In Delphi it was a TService descendant, but now i want it to just be a
normal console program, which I can run as a service under Systemd on
Linux.

Then while chasing a strange error concerning wsmenus I changed from
what it was in the beginning to nogui.

Now I do not know how to cancel that change and get back to what it
was before (it needs to be a console app and dual platform).

There 13 different "widgets" offered and I do not remember what it was
in the beginning. So which do I choose for a dual platform
(Linux/Windows) application?

Concerning timers the old application I am porting makes heavy use of
TTimer objects, there are probably a lot more than the 4 I have in
this constructor.

So I should change the timer class from TTimer to TfpTimer or some
such?

I assume that is cross-platform, right?
