after spending over one hr on this, I gave up. I open a text file. make it show line numbers (view->Line number). Now I want to tell textpad to save this setting so that I do not have to do this each time I open a text file again. Yet, I am not able to find anywhere how to do this simple task.
I am using texpad 7.4.0 on windows. I looked at configure->preferences->text and I do not see anything about show line numbers.
Go to Configure > Preferences. From the left side menu options, select View and make sure Line Numbers is checked. Press Ok and you are good to go.
