I copied a tex file from another project and it is strange that there is no compiling but only two buttons, refresh and download. How to compile the file like others? do I have to upload from local computer?
This is the steps:
Click upload button –> choose from another project –> choose a project and a file –> create

Unfortunately, it's not possible to use imported files as main files, only files that are editable in the project can be made main. The intended use of this feature is to bring over e.g. custom packages, bib files etc. across multiple projects.
