SLightly off topic, but what I've done for ages is to use the Reading List plugin for this purpose. I have one list that is flagged as the default within the plugin that is defined as:
Code:
Name: Sync Later
List Type: Manually add/remove items
Device to Sync To: Kobo Glo (main) <-- This is my standard eReader; others exist but only for testing purposes
When Syncing: Add new list items to device
Sync to this device as soon as it is connected: Checked
Clear this list after a sync to this device: Checked
The Reading List plugin has also been added to both Context Menu's and both Main Toolbar's. This way, when I see book I want to sync, I can right click on it, select the
Reading List option, and then the
Add to Sync Later List option. After flagging all books I want ifmy Kobo is not plugged in, plug it in and let the sync happen automagically, or if it IS plugged in, select the
Sync Now option.
