I don't understand what is the meaning of Options -> Incoming Mail -> Preview mode settings -> Apply filtering rules when previewing folders.

First, I don't understand the difference between open and preview in this case. When I click on a container and I see the list of contents, I call that an opened folder. I call preview the thumbnail of a pdf in a folder, or the print view in MS Word.

Second, I don't understand why an option concerning filters is there and not in Filters.

Third, I don't understand how it coordinates with the "when folder is opened" parameter of filters. I'm imagining several solutions, but it seems to me so complex and of such a rare use that I doubt what it is.

If I understand well, Pmail began with floating windows, and then there was pressure to add a three frames display a la Outlook Express. Personally, I like the floating windows, that's one of the reasons why I keep using Pmail.

Presently, there is a button in the top bar of the Folders window, with the choice to toggle between "Preview" and "List". I find several minor problems with this button:

1) Although the icon is explicit, the words "Preview and "List" are not explicit. When I can view a message from top to bottom, I don't call that Preview but View. I also find it difficult to call List an action that will conceal the list of messages in the folder I was browsing.

2) Maybe the icon bar of the Folders window should contain only icons for actions on folders, and the Preview/List button should then become a choice in a View category of the application's top menu. Other MSWindows apps do it that way.

But, more important, I note that, if I have the Folders window and the New Mail window both open and floating, when I change from Preview to List, the three frames window will overlap the already opened New Mail window. Which is embarrassing, especially if it is New Mail I am browsing in the three frames window.

I think it would be brilliant if I had the ability to move the windows and "glue" them together, like magnets, just by making them touch each others. And of course "unglue" them the other way round. I was imagining for instance the identity card of a sender popping up when I open his message. I prefer it glued to the message, not glued...

 Then of course Pmail would remember my choices.

I had never noticed this before. I think the choice of the word "embarrassing" is appropriate. I understand that many people wouldn't switch modes very often, but when one does, this is a poor showing.
