How to disable lines around text and explanations in Sublime Text
I have these lines around text and explanations popping up annoyingly. Is there a way to turn these off?
I tried to look in settings and to adjust them but nothing works out.
P.S. ignore the code, it's just for example
White lines surrounding code like that are generally indicative of something like a code linter or other similar tool giving you an indication that there might be something wrong with the code (such as not following a code convention of some sort). The code explanation is a popup showing you the arguments and documentation for whatever function or method you're working on.
Both of these things are something that Sublime doesn't do on its own; you have installed a package of some sort that provides this capability.
If you were looking in the regular Sublime settings (Preferences.sublime-settings) for options that control this, they won't be there. In order to configure these away you would need to determine the package that you installed that's doing this and then configure that package not to do it or, if that's not possible, remove it.
If you use Preferences > Package Settings > Package Control > Settings - User from the menu, you can inspect the installed_packages setting to see what third party packages you installed and investigate which one of them is doing this.
Possible packages that do something like this would be Jedi or one of the Anaconda packages; essentially anything that says that it provides code support and assistance for Python is a candidate here.
Once you find the package in question, you can look in it's settings directly to see if you can turn the features you don't want off; failing that only removing the package will stop it from displaying these things.
