Hi
When the preview pane in enabled, there is a delay of several seconds between selecting a message and being able to delete it. The reason, it seems, is that the delete command is ignored while the message is loading.
If you just want to delete a message without displaying it you can use CTRL+Click to select the message row and then delete.
which is actually "add to selection" and therefore problematic if you already have another message selected.
Thanks to everyone for their input.
The control-click solution works well, but unfortunately it's difficult to communicate to customers. Perhaps one of these days we'll create a "tip of the day" plugin for useful tricks like this!
The ability to hide the preview pane without having to go to user settings is really helpful, and this is the way I tend to deal with it.
Thomas suggested yesterday that the source of the problem is our Imap backend rather than Roundcube. However, I have done some more testing and found it to be significantly slower than our old webmail - though not quite as slow as I suggested in my original email. In the old application, I can page through around 20 messages in 30 seconds, but in Roundcube I can only read around 13 messages. This is not very scientific, but does suggest there's room for improvement.
I'm planing to do some performance profiling of Roundcube soon, and will share the results with you all.
Thanks
Marcus
