I expected this, since the launcher is a specific feature for the Nexus 5. Having tried it already I can honestly say I will not be missing it.
If you own this device for more than a year, you'll come to appreciate the translucent bar. Both my Droid Incredible and Galaxy S II (both OLED displays) had the notification bar burn-in over time.
Not happy about this one. I use ES a lot for moving files from my internal SD to my external SD.
I've already sent a detailed report to ES Group. Hopefully they address it. In the meantime, you can access the sD card via ES File Manager (located at /mnt/extSdCard), but you can only read files. No create/delete/edit allowed.
For the life of me I cannot find anywhere in a search when that feature was added (for 30 minutes I looked lol), but I've been using it for quite some time (even before I rooted). My boyfriend is using it on his GE S4, and he hasn't yet received the 4.4 update yet. Unless we're both talking about something completely different, which knowing me at this hour is highly probable hehe.
It was not there in 4.1 (SGS2), and I did not notice it in 4.2 nor 4.3. Doesn't mean that it isn't/wasn't there, just that I've never noticed it.
Please share more when you can!
Here's what I've got so far.
ART makes a subtle yet HUGE difference. First,
here's my simplistic explanation on what ART does.
After getting the OTA, I played with the phone for about an hour then did a factory reset. I turned on the developer options, enabled ART, and used it for about 48 hours. I then turned off ART for about 48 hours. I went back to it today.
During the 48 hours without ART, I craved it. The S4 GPe is a very smooth device, in terms of Android devices, but it is not as smooth and fluid as my wife's iPhone 5s. With ART, the gap narrowed. I got use to an ultra-smooth device with VERY few hiccups. It's still not like the iPhone 5s, but it's damn close. Turning off ART kept the phone mostly fluid, but those hiccups were far more frequent and far more often, ESPECIALLY in Google Chrome.
ART is a runtime for Java-based apps and has no direct effect on native apps, which most of Google's apps are. However, if a background app uses Java, they can still slow your foreground app, and in these cases is where ART shines.
Overall, I'm more pleased than displeased with the update and would not want to go back to 4.3. KitKat is full of many subtle differences, but the net effect is rather large. There's a good chance that the GE Launcher is coming to more devices (it's been hinted as a temporary exclusive for the Nexus 5). This, combined with the supposed camera improvements in the pipe would make me very happy.
