The compose window is currently formatted as follows:
1. Top of browser window: "roundcube" + row of icons
2. Left of browser window below (1): pane 1 "contacts", about 20% of the width of the window, remaining height
of the browser window.
3. Message header fields, below (1), right of (2).
4. Center of browser window, right of (1), below (3): pane 2 "text entry box", about 50% of the width of the browser window and extending to the bottom of the browser window.
5. Right of the browser window, right of (4), below (3): pane 3 "attachments", uses remaining browser window width and extending to the bottom of the browser window.
There are width adjustment handles on "contacts" and "attachments". With those I can make them narrow, but I have not been able to make them go away.
I want "contacts" gone always - I never use that. In a new message I just start typing the address in "to" and it offers matches from the address book to select. Similar for CC, BCC.
I want "attachments" gone unless there are attachments present. The paper clip icon is available to start adding them, so there is no reason for the huge empty "attachments" window to be around, just to access the redundant (with the paper clip) "+" in its lower left corner.
How does one do this? There does not seem to be anything in "settings"/"composing messages" that would change the format of the two extra panes.
Thank you.
