It will be very good for me to have a possibility to combine some tabbles ASAP (without delay caused by file access) and then wait a bit to get filtered list?
I don’t understand… it should already be like that. When you open a tabble, first the combinable tabbles are displayed in the main body, and only then the disk is accessed and the file list is built and displayed. So you can easily double-click and combine a tabble before the files have been displayed.
There is no access to the disk until after the combinable tabbles are displayed.
(The above is only true when you opened an ordinary tabble. It does not hold when you have opened a folder-shortcut, aka folder-tabble).
