I have often wondered if anyone at Apple used a multi-monitor setup. Sure, having the menubar on one screen maximizes the screen real estate of the additional monitors. But you lose a lot of the convenience and simplicity for which Apple is known.
I tried SecondBar and DejaMenu. Both are nice applications. DejaMenu hasn't seen an update since 2007. SecondBar is in active development and demonstrates another way of addressing the menubar issue. However, my own impression is that SecondBar doesn't feel as well integrated.
I am impressed with Hisham's (Binary Bakery) attention to addressing this issue and his focus on making it as elegant as possible. I am fairly OS agnostic. I use Windows, Linux, and OSX and often experiment with other hobbyist OS platforms. I believe that developers who add functionality to the OS or the window manager on Windows and Linux often have an easier time of it as their interfaces are not held to as high a standard for unity and elegance. MenuEverwhere is a well-integrated solution to the need for additional menu bars. And, it looks nice.
So, what are my niggling issues with the program?
I want to use the borderless style (I believe it will appear less cluttered) but on my system the borderless buttons are not vertically centered within the menu bar. They appear to float to the top which is a bit jarring on OSX. I'm sure that on Windows or Linux I wouldn't even notice this issue. In the meantime, I'm using the rounded buttons until that (admittedly minor) issue is addressed.
Because Adobe adds a number of non-standard controls to their application windows, Adobe Creative Suite requires activating the menu via a hotkey. I don't mind this. In fact, I appreciate the work around as it seems to lend itself better to my workflow while doing design. I often use my Adobe CS5 software on a large external monitor and need access to the menu bar. It's nice that I don't have to leave the work area to access the menu bar.
The window-integrated menubar menus can be pretty slow to appear in some applications (the "Bundles" menu in Textmate, for instance). Sometimes menu items in the window-integrated menubar are grayed-out that are otherwise accessible through the regular menubar (again, Textmate is where I noticed this). I suspect that these issues are fairly application specific and probably not common as I haven't observed the issues in many other applications, yet.
Each of these issues are minor. In the case of Adobe CS5 I actually prefer the hotkey access to the standard menubar as it is such a nice complement to the contextual menus Adobe already implements.
Binary Bakery's MenuEverywhere addresses one of the most annoying issues with using a dual/multi-monitor setup on OSX. It is one of those small things that can make a big difference in helping you get your work done. I've only used it for a short time but I decided to purchase it this morning.
Hisham, thank you for continuing to work on this utility.
