in the body of editor i see lines, that shows border of if and else operators and at any time you can minimize or maximize this if else, not use comment ;{ ;}

Change the preferences for Editing by unchecking 'Enable bolding of Keywords'.

Yes, I had this issue at first too.

You have to make sure, in most cases, that you are using a monospaced font. Where all characters are the same size. Bolding and other styles can affect this.

I use the Font "Consolas", Style "Normal", size "9"
I also am able leave "Enable Bolding of Keywords" activated.
