Day 69: Log console

Today I added a few commands to the shell, then I proceeded to implement a Log console, which is basically an output console on top of the shell.
I managed to make everything work, and I can also scroll up and down to see older output messages, and so on.
It is not perfect yet, but it does the job.
The shell can control the log as well, for example by changing it color, and with the tab key it is possible to enable or disable them.
In the picture I redirected the fps output I was printing on the windows prompt directly to the Log console, and it works perfectly.
Tomorrow I'll probably try to solve the little problems I have left behind.
