Please review my first PCB schematic | ESP8266 + led-strip

Question

I wanted to create module based on ESP8266 to manage led-strips. Since I have both RGB(WS2811) and white LEDs I wanted to create universal PCB to be able to use both kinds of strips.

Here is schematic:

I did some tests on breadboard with ESP-02, DC-DC converter and RGB, but since I didn't have anything else I couldn't test how switches are working, how mosfet is handling white strip and if resistors are placed correctly.

All missing parts are ordered now, but since it is few weeks of waiting I thought I could order PCB as well. Because this design wasn't tested I wanted to ask you for review and some suggestions before I send it to OSH Park.

https://hackaday.io/project/5646-5-wifi-rgb-enabled-led-dimmer-w-esp8266 was an inspiration for me.

EDIT: schematic updated after suggestions from Olin

1. I'm not a fan of your component naming scheme. Naming resistors things like "RESET" and "PWM" is confusing. There is a reason a convention has evolved. Not using a common convention is annoying to those who are used to reading schematics and who you are asking a favor from. Beginners don't get to make their own rules.
2. There is nothing indicating what the ESP-07 part is. It seems to be some microcontroller from context, but the part value should be shown on the schematic, and the part named IC1 or something.
3. The logical flow thru the 5 V regulator is drawn backwards. Apparently 12 V is coming in from a wall wart jack, and the regulator is producing 5 V. The 12 V should be coming in from the left, and the 5 V coming out of the right side of the regulator.
4. Both the part name and value are missing from the regulator. The name should be something like "IC2", for example.
5. Is the regulator really a isolated DC-DC converter, as suggested by the separate OUT- and IN- pins? That would work, and perhaps it's what you had in the junk box. For a volume design, that's real waste since you aren't using the isolation. A buck converter would be significantly cheaper.
6. Shouldn't there be ceramic caps immediately on the input and output of the regulator? If it's a isolated DC-DC power module, then maybe they are built in and you don't need them, but that's not clear from the schematic.
7. There is no bypass cap across power and ground at ESP-07.
8. What's the point of pulling down the GPIO2 pin externally? It's not used anywhere. If it really is GPIO, then you should be able to set it to output to keep it from floating. If it is input-only, then it is mis-labeled in the part.
9. It's not clear why you need the 0 Ω jumper across the FET. Since the firmware controlls the FET, it has the option to turn it on whenever it wants, including all the time.
10. You might want a weak pulldown on the GPIO13 line to keep the FET from glitching on during powerup.
11. 10 kΩ is excessive for driving the gate of the FET. The resistor name implies this line has a PWM signal on it, so you want fast edges. I don't see the point to the resistor at all. If you need a resistor in series with whatever gets connected to the middle output pad, then put it between the FET gate and the pad, not between the micro and the gate.
