So I have been using the new asset forge for a little bit now and here are a couple features I think could be useful

Click & Drag Selection - It would be very useful to be able to click and drag to select any blocks that contained within the selection. Maybe SHIFT+Click & Drag select any and all blocks that are touched by & within the selection, where as default Click & Drag only selects blocks that 100% within the selection.

Group Naming - Since you can name groups with lua scripting, it would be nice if this was also possible by simply clicking on a group and then maybe right click on it for a list of options, like group properties.

Export Selection - Be able to select blocks within your project and export just them.

Export Groups by Name - Would be really cool if we could also say to export each group to their own file based on the group name

Scroll Wheel in Model Selection pane - Be able to use the scroll wheel to change which page we are looking at on the model selection pane. This would feel more natural I think and speed up workflows.
