DoItAll is an addon which will use the currently "shown" (unfiltered items in inventories) items and mass move/add as attachment/trade/deconstruct/refine/extract them.

It therefor respects FCOItemSaver marker icons and protects your items the same way like it is done with manual tasks.

With the DoItAll standard settings ALL items marked with FCOIS will be protected and not touched!
With the DoItAll settings changed to "Respect FCOIS panel checks" it will check each marker icon and panel (deconstruct, mail, bank withdraw, etc.) and will move/deconstruct/attach/... the items which are allowed at that panel (depending on the settings of the FCOIS marker icon -> See FAQ about dynamic marker icons).

Unmarked items (no FCOIS marker icon applied) will be just always moved/added as attachments etc.).

Example:
To be able to mass mail items with FCOIS marked icons:

1. Add marker icons to your items to protect them
2. Open the panel where you want to use DoItAll
3. Filter the items by the help of inventory filter addons like FCOItemSaver, FCOCraftFilter, AdvancedFilters Updated, Harvens Stolen Filter, AdvancedFilters dropdown filters,Craftbag Extended to only show these items which you want to add/trade/bank/withdraw/mail.
4. Click on DoItAll button or use keybind and it will only respect the currently SHOWN/visible items.

If you want to have items added to the mail first check the DoItAll settings to do the extra panel checks within FCOIS!

And then e.g. define a new FCOIS dynamic icon, give it a custom name, and disable the Anti-mail protection. It can be then added as attachment as it is not protected against mail anymore.

You can also use any other existing dynmic icon and just change it to allow to be mail attached.

Or for the non dynmic icons check the FAQ for the "additional inventory context menu flag buttons" and right click it at the mail panel so the anti-mail checks are disabled (red flag). This allows DoItAll to skip the anti-mail checks as well (it wil still check dynamic icons though!) and add the marked items to the mail this way.

Works the same for other panels, like bank withdraw, bank deposit, player2player trade, inventory destroy, decon, improve, retrait, ......
