I've posted how to highlight in evernote client for the mac in this thread earlier but it's a pain in the ass to do so. I highlight almost every day, and I agree, it's the most basic of functions for note taking software. Even iOS and Android clients have this feature but the desktop client does not. First let me just say that I love evernote and the team has done a good job, but there are 2 things that have really bothered me about this software.
1. highlighting (most basic function of note taking)
2. speed of software
As a software entrepreneur, this leads me to believe that evernote has some core problems that reminds me much of microsoft type bloatware that I had to use in the 90s and into the last decade. The truth is I use evernote mainly because there is no other replacement for it that's cross platform and where I can carry my notes everywhere. I use my mac, PC, iOS and Android devices on a daily basis. They keep adding features to the software that I rarely use which I believe makes the program bigger in size and slower for devices. I realized that it wasn't my computer that was too slow having recently upgraded to the new macbook pro retina and iphone 5. It was evernote that was slow.
The thing I love about google is that they are obsessed with speed. Speed of search. Speed of execution. Speed of results. My wish for evernote is that they focus on speeding up the software so it feels light and nimble plus include highlighting of course I'll never forget Steve Jobs keynote when he announced snow leopard. He said that they mainly focused on speeding up OS X and making it more efficient. That blew my mind. When I upgraded, it freed up about 12GB of hard disk space and OS X was faster. I was in heaven.
Some examples of software I love who are obsessed with speed (and light memory footprint) is: Dropbox, utorrent and chrome
