a. When creating a file or folder from the projects folders using right click New File or New Folder it doesn’t automatically add the created files/folders in the project folders.

b. tab_size:2 and translate_tabs_to_spaces:true from Global.sublime-settings doesn’t automatically adjust once you open a file that is created from other editor having tab_size of 4. So when you create a functions under a class tabs is automatically following the tabs to 4 also.

With regards to ‘a’, it will if the current file system sends notifications, which is generally the case. In many circumstances, such as remote folders, this won’t happen.

For ‘b’, it sounds like you also want to set the detect_indentation setting to false.
