all opened files should always have a tab

currently you need to double-click a file on the sidebar, or open it via the file open dialog, in order for it to have its own tab. 

if you just single-click on a file, you see it in the editor, you can edit it, but it doesn't have a tab. This is confusing because you don't know for sure which file is opened, especially If you have similar files.
This is the file preview feature (not a bug). If you start editing the file it becomes its own tab, at least for me (version 2063).
you're right, hadn't noticed that.
