To maximize editor space I like to hide Tabs, and instead use the “Open files” in the sidebar. The problem is that once you start working with the file tree, the opened files part of the sidebar is quickly out of sight due to scrolling.
I would like the opened files to remain visible, since it’s of great help when navigating between them. The basic idea es that it works like the normal tabs: the current opened file should always be visible, and the ones around them too. Maybe we can have some sort of separation from the file tree that can automatically span when there are a lot of opened files, maybe up to a maximum of half the screen or something like that before showing scrollbars.
