I'm working on a big new mashup that includes data sourced from Google Calendar and Spreadsheets. While putting it together I've noticed a couple of issues.

I'm pulling feeds from Spreadsheets and Calendar, but the GME cache for both sources isn't updated frequently (*maybe* once or twice a day). The usual trick of sticking a '&timevariable=[date/time variable goes here]' at the end of the feed address doesn't work, as Spreadsheet & Calendar have strict parameter passing requirements (which return an error of you add extra variables). It would be *really* nice to be able to set a parameter in the gm:data tag that specifies the frequency of cache refreshes -- particularly for SS and Cal. Even if it's coarse grained like 30mins / hourly / daily.

Also, I've noticed that the gm:link tag implies a trailing <br/>. In other words, you can't string a bunch of these links together on one line of text; and if the linkref field is empty, nothing is displayed -- it would suit me better if the link was disabled rather than hidden if no link ref is available. Could that maybe be an option?

Thanks! Reto
