Question: I have just started using KiCAD (with no other experience e.g. in Eagle). I was basically able to put together a schematic and layout a board but I am struggling with some footprints. How would I search for, e.g., a footprint for [these](http://www.ebay.de/itm/170844394043?ssPageName=STRK%3aMEWNX%3aIT&_trksid=p3984.m1497.l2649#ht_1915wt_1163)?
Can I expect footprints somewhere in the library for most components or is creating my own a common task?

Answer: 
I use Eagle and, despite its huge libraries, most of the time I prefer to create my own footprints since I can adjust them to suit my needs.

For example, I usually use a 0.25 grid and the 0603 capacitor as it is on the library doesn't allow a 0.25 mm trace to pass between pads with a 0.25 mm clearance without warnings so I redesigned the footprint so it generates no warnings.

Besides that, it is common not to find the components you need on the libraries or to make slight modifications to adjust them to your design preferences.
Make your own footprint from data available in the data sheet for the component you're using. In the long run, you'll spend more time making sure libraries you download are accurate than you would spend just making your own correct footprint.
