It is very difficult for our users to select all images in a folder when using a tablet. With the old dialog we used (Delphi's own TOpenDialog), you could select Organize > Select All. However, your dialog does not have this or a similar option to allow a user on a tablet to easily select all images.
Obviously they cannot do a CTRL+A like you can if you had a kbd. Even a mouse drag to select them all is hard on a tablet with no mouse.
We can't use Delphi 2007's dialog due to a error when previewing is enabled on some tablets like a Surface 3. So we moved to using your dialog since it did not have this error.
Can a select all be added to this control or do you have any tricks I can implement quickly?
I just updated to the latest, and was sad to not see this option yet, or maybe I missed it. Hopefully it was just something you didn't have time to get to rather than not possible.
