Currently, the application supports multiple open windows, and multiple tabs in each window.

If a user wishes to open a new file, the general possibilities include creation of a new window, or of a new tab in the existing window. Which possibility occurs in a particular case depends not on explicit direction by the user, but on the manner in which the the file is selected.

If the file is selected through the menu, a new window is created, whereas if it is selected by side bar, a new tab is created. It is unclear whether this behavior is generally desired. Perhaps the intention is that each window corresponds to some directory tree, represented by a sidebar, from which files might be opened in new tabs. Yet, from this particular distinction might follow the conclusion that opening a new file, as opposed to a new directory, from the file menu corresponds to a preference for creating a new tab, compared to the current behavior for this case, of creating a new window.

In fact, while some users may prefer use of multiple tabs, some may wish for only one open file per window. A mode of operation that excludes tabs might produce a behavior of creating a new window for files opened from the menu, yet replacing the current editor buffer for files opened from the sidebar.

While it may be unclear precisely which design ultimately might prove optimal, the topic appears appropriate for discussion.
