The error handling in the current code is incomplete, and logging library could be used to handle errors and logs.

Consider Zap - Uber-go

*This it to learn logging library and error handling better in Go

Currently the output section of UI under the Command menu does not support multi line.

Can't save changes as well

HTML syntax like " are not being escaped and cause display to not work properly.

etc.

Currently auto complete is hard-coded, user unable to modify setting

Add a feature so user could set output to something like:
`fmt.Println( "test {c:}" )

And after output, the cursor position will be at {c:},
and {c:} will not be in the output

Redesign code for shift and caps lock state.

Remove the need of constantly passing shift and caps lock state(bool) around.

Command will try to detect the max command.

Ex:
Command buffer: abc123
If command is 123, current code is unable to detect this last 3 characters '123'

Assuming:
Command: /t
Output: fmt.Println( "test" )

Add ability for user to enter commands with arguments like
/t{1:123}
where {1} is just an example of the argument, and user set the output to:
fmt.Println( "test {1}" )

and the output could read the argument and output it together to:
fmt.Println( "test 123" )
