We were burgled in February - sounds very like your burglary, except they jemmied open our French windows at the back (old, wooden frames). It was also broad daylight - between 12 and 4pm.
They went through most of the house, but were only looking for jewellery and money. (they also took our passports and some credit cards).
The police said this wasn't unusual - thieves tend to specialise in the items that they nick. Jewellery is also easy to just chuck in a bag, of course.
We had a better lock fitted on our back door - 5 lever lock rather than the 2 lever lock that was there before - and some extra bolts.
I am planning to get some plantation blinds fitted in the front window, so that no-one can see in from the street to gauge whether or not there is anyone in. Our lounge/dining room is one long through room, and you can see in from the street - it can look as if the house is empty. I work from home a lot, but upstairs, so now I'm scared that it might happen when I'm actually in.
I have been working downstairs with my laptop much more often, or make sure that the radio/tv is on downstairs if I'm upstairs, so that there is at least some noise to put them off.
Thankfully most of the jewellery I had stolen wasn't especially valuable (although there was a lot of sentimental value attached to it), and I'm getting a nice, fat cheque from the insurance company to replace it.
One of the things I wish had done, and which I must do with the stuff I do have, is to photograph it. I have receipts/valuations for a lot of my nicer pieces, but no actual physical record of it, and this would have made it a lot easier for the police to try and trace it - and also a lot easier for the insurance company to value it.
Our big items, such as TVs, X-boxes, etc were not touched - but they are all marked with Smart Water (which our police supplied for free), and we have a sticker in the front window warning likely burglars of that.
