I did not find what app I was going to help me
I want to change things in about (I’ve added an image to the menu I’m talking about)
I am talking about change I mean in texts, links and other things that are there
And I did not find anything in settings or anywhere in the system because that’s why I turned for help.
With a special app (that you would need to create, or ask somebody to do so), you can add additional features that can also show up in the menus. You might ask in the app developer forum to what extent you can change menu.
The texts are in the code. And of course in the translation system which is managed on transifex. Now it depends if you just think a text is not good or badly translated. In those cases, I invite you to github (for the main English version) or transifex (for all other languages) to share the better version. If you just want to change it to anything you want, you could either change the text directly in the code, or perhaps copy the language file and create “your own language”.
