Migrating semi-pro studio from windoze

Of course I'm willing to colaborate and I understand that you are busy! :D

Folder tracks is just for organization to be able to expand/collapse groups of tracks. You could leave the additinal features for the moment (mute, solo, arm record. when clicking on mute for example every track in the folder is muted and so on). The important thing is to create a folder track and then drag and drop the tracks over that folder to associate them. You could also create a sub-folder track inside another to create a tree, but this could also be left to a later release.

This is an explanation of the use from a commercial software.

"The simplest application of a Folder track is to allow you to reduce the number of tracks shown in the Project window without having to delete anything. To open or close a Folder track, simply click one of the Expand/Collapse Folder buttons on the Folder track itself, in the track list: either the small +/- button at the bottom-left of the track, or the small folder icon. Alternatively, to open or close all Folder tracks in the track list at the same time, hold down Control/Apple when you click the +/- button.

You'll notice that Folder tracks have similar controls to regular tracks, including Mute, Solo, Record, Monitor and Lock buttons, and using any of these controls affects all the tracks contained within the Folder. For example, pressing the Solo button will activate the Solo button for all the tracks in the Folder, providing a quick way to solo different groups of tracks in your Project. This is particularly useful when you're working with a large number of audio tracks that all need to be record- or monitor-enabled at the same time: place the audio tracks in a Folder and use the Folder's record and monitor enable buttons. Finally, the Folder track's Lock button is also a convenient way of locking the entire contents of a Folder with a single click."

Here's some example pictures:

So we have the requirements:

1. Create folder track
2. Remove folder track (removes all the tracks in that folder/removes the folder track and de-associates the track with the folder and puts them in the "root")
3. Expand folder track
4. Collapse folder track

Much of the times you don't have to for exampe be able to solo the folder track as you mostly have the one to one structure of the folder tracks with the mix busses. For example I create a mix bus "Drums" where I route all my drum tracks, same for vocals etc. But this feature is nice when you don't have one to one relations so I recommend this to be added to a future release whenever there is time to implement it.

Optional features (later release)
5. Solo folder track (solos every track in the folder)
6. Mute folder track
7. Arm record folder track
8. Show the overview of containing clips in the "clips area"
9. Create sub-folder track (same structure as folder track, just to organize further. for example I use the structure below to be able to mute/solo just the lead vocals, etc)

-VOCALS
--LEAD VOCALS
---LEAD VOCAL 1
Lead Vocal 1 Left Track
Lead Vocal 1 Right Track
---LEAD VOCAL 2
--BACK VOCALS
---BACK VOCAL 1
Back Vocal 1 Left Track
