Mail searching with pre-defined date interval

I just committed a small Roundcube feature that adds date interval selector to the search options popup. IMAP search query using BEFORE and SINCE keywords will be generated from the selected interval option.

See it on the screenshot.

On the screenshot you can also notice another small feature that will be part of Roundcube 1.2. It is a messages list page selector, you can use it to directly jump to the specified page.
