I normally use Path Finder as my current finder app but since Yosemite it no longer visually fits the theme of OSX.
The new finder looks great but lacks a lot of the features Pathfinder has such as dual window browsing, tabs, drop stacks, multiple side bars, highly customizable toolbars, built in unzipped, text editor and pdf viewer amongst many other things.
It strikes me that Finder hasn't really been updated since Leopard other than adding tags. Why have Apple neglected one of the most important facets of the OS?
1) It's easy enough to just open 2 separate windows
2) The Finder does have tabs (as of Mavericks)
3) Not sure what drop stacks are
4) Don't know why you'd need multiple sidebars
5) Actually the Finder's toolbars are quite customizable... you can put Apps, AppleScripts, Documents and more in the toolbar
6) Double click a zip file... it unzips not sure how this is different than being built in
7) I would argue that Text Editing is best left to a dedicated Text Editor. If need be to view a document, just press space bar to use Quick Look
8) PDF Viewer - just press space bar to activate Quick Look, also PDF documents are rendered in tiny versions in their icons (which you could make very large) as well as in Column View and Cover Flow
sorry but this alleged lack of features may just be the result of not understanding how to use some of the features it does have. I am by no means bashing third party tools like Path Finder - they certainly have their place and offer choice to users, but to say the Finder is so "lacking" far from an accurate statement.
