we cannot see (in the task list), whether a task or subtask has any attachment or file.
why would that be helpful?
if you are searching / looking for photos or files inside a project, anykind of overview where this data is stored, is very important.
to have just an overview of all media - like we have now - is not satisfying (if you have several hundreds of photos).
this kind of overview is standard in e.g. all CRM apps (pipedrive, hubspot etc.), where you may see all attachments for any email you ever wrote or get to/from someone.
so it is just a list showing which list item has any data …
