You&#x27;re mixing up arguments. No one on your team should be changing indentations. You should decide as a team what your settings are going to be, that&#x27;s why I suggest using DetectIndent to make sure your settings match whatever the project guidelines are.<p>It&#x27;s not a matter of personal preference though. Tabs are simply superior for encoding indentation. If you use tabs for indentation you can configure their width in your editor to match your personal preference, spaces doesn&#x27;t allow for that. That&#x27;s the only significant difference, and the only good reason for using tabs instead of spaces.<p>None of the arguments you made about spaces make sense. What&#x27;s the fact that sometimes people mix up tabs and spaces got to do with anything? The whole idea of using tabs is that the code <i>does</i> format well regardless of what tab-width setting you have on your machine. Converting tabs to spaces <i>does not</i> require manual intervention <i>at all</i>. Alignment should be done with spaces, no one is argueing to use tabs for alignment. You can&#x27;t use tabs for alignment because their width is undefined! The whole idea of using tabs is semantically encoding the authors original intention to allow you to reformat as you wish! At this point.. are you just trolling me?
