Just published Preview Tabs.
It does sublime-style file previewing, where files are opened as a ‘preview’ until they’re modified, saved, or double clicked. This lets you quickly look through several files without opening up a lot of tabs.
Also, it relies on various events, meaning that the tree and tab packages do not need to be disabled, and them being updated are less likely to break this package.
Let me know if you run into any issues with it. Thanks!
