1629715 - Dragging messages is user-unfriendly (target invisible)

Status: RESOLVED DUPLICATE of bug 1464540

(Thunderbird :: Folder and Message Lists, enhancement)

Description

[Ulrich Windl]

Attachment: Screen-shot showing big non-transparent "drag box" while moving messages

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

I marked two messages, wanting to move them to a different folder via drag & drop.
(Thunderbird 68.7.0)

Actual results:

Instead of two message lines (as expected) a big non-transparent box appeared (see attachment), making it impossible to see where the drop position (which folder will be selected) is.

Expected results:

Every other program I know has a better dragging implementation than Thunderbird has. Why not outlining the block of messages selected, allowing to see where the pointer is moved to (and which folder will be selected).
