comment Tracing Boundary Around a Polygon Shapefile in QGIS
Zach, I think you misinterpreted the 'avoid intersection' feature (as per my blog post you mention.) It will not do what you want here. In this case, using that tool, you would have to trace along the outside manually, and then it would just fill the inner 'white' spaces, 'avoiding' the yellow areas - not what you want. – Darren Cope 8 mins ago

comment Why does ogr2ogr silently skip some rows?
Can you create a second .csv with all records, but strip out all of the columns except the ID and lat/lon columns? Try to import that, and see if all records come in. Sometimes there is an improperly delimited row somewhere that will confuse things, and is hard to pick out visually...

comment How to use centroid option in Field Calculator in QGis
I'm interested in seeing if there's a 'real' answer (without a workaround) to this question now, as I see there's a 'centroid' function in the field calculator which I don't think was there before. However, I played with it, and am also unclear on the syntax. Perhaps there is a better answer to this question after all, using 1.9.0 Master.)

comment How to create a customizabe table in QGIS Print Composer?
Thanks @RyanGarnett. I'm on a Windows7 machine, 64bit dual-quad core i7 with 8GB of RAM. I tried the SimpleSVG plugin, but it of course doesn't work with the 'new symbology' options, which my map is using.

@RyanGarnett; Yes, I have tried working in Inkscape, but for some reason it is just painfully slow on every computer I've ever used (including this one, which is quite well-equipped.) It just wasn't worth the frustration. Any good tips for SVG that make it actually usable?

Sorry, forgot to mention that I am using QGIS 1.9.0-Master. I am aware that I can add .html (that's why I mentioned it) but was curious if there's a better/easier way.

comment How does manual Label Placement in QGIS 1.9 work?
Actually, I just figured it out. You must have a column set so that the "Show Label" option is data defined. Integer seems to work fine, with 1 meaning visible, and 0 meaning hidden.

comment How does manual Label Placement in QGIS 1.9 work?
Great! I had all of that figured out already, but couldn't figure out the 'pinning' concept. It turns out that when you manually modify a label, it is 'pinned' and then you can modify it as SS_Rebelious says. The only part I don't understand is the "Show/Hide" labels tool, which I cannot get to activate. Perhaps because I already specified "Show all labels"?
