I'm in the middle of a lengthy filing exercise on several years of mail. Most of the time I can only use one hand and can't sit up for long, so selecting messages is more of a problem than Thunderbird is designed to cope with. Most of my other file handing programmes, and even my ISP's web mail interface, have checkboxes to make one handed selection of files much easier. I am quite surprised that, though Thunderbird has been provided with other tags, like the stars (can't use these for selection because I'm already using them for importance), nobody seems to have come up with a simple check box add on. I'd really appreciate it if someone were to make a simple add on to provide this functionality. Also, as I've been doing some spreadsheet work, as well as filing the mail, I keep finding myself wanting to add a note to emails, to remind myself of what I done with them, or as a reminder of their contents, or where the original is filed, and other things that might occur to me, that I would like to label the message with, but without editing it. I want these notes to pop up like the little note flags that I can add to Excel cells. It would be great to have these hover over notes to help me pick the right mail, without having to open it. When sorting and filing, I like to maximise the number of messages I can fit on my small notebook screen, so I don't find the preview pane very useful--and don't really want to see more than a small note, that isn't part of the normally visible message. A properties sheet for each message as we have on ordinary files and photos, would be a good idea, but I really only need the note pane, at the moment. It would be great if these functions/refinements could be added to Thunderbird, to make it easier to use, for those with restricted movement and space. Maybe someone has thought of the note/labelling idea before, and knows of an add on that might do the job. Many thanks, S
