[enhancement] diary collapsed by default

[victorjagu]

Hello sirs,

Just wondering if it is possible to add an option to set the diary view as collapsed by default, or at least that remember the last setting.

When I ate a lot of different stuff for a single category (let say lunch), once I have finished adding meals and food I find the breakdown too overwhelming, and if it's collapsed I can see the total calories eaten, so that's perfect.

As a workaround, I'm currently using the "not show thumbnails" option, which helps somehow, but having it collapsed would be better to my needs.

Anyway, this is very personal, so just a kind request in case there is a little time to add this in the future.

Thanks!!
