Idea is to replace the toolbar with a set of bookmarks, assigned by middle click, middle clicking with an item in hand, or by dragging from the crafting menu.

Advantages

• Displays total count of items in inventory, not just whatever partial stack is on the toolbar
• Works even if bots steal your last item
• Allows you to automate production of an item and place blueprints without picking it up yourself
• One item can have multiple bookmarks without getting confused as to which slot has the stack or wasting space with extra stacks

Disadvantages

• Less total inventory space (but this can be compensated by increasing the main inventory)
• Less ability to subdivide stacks before ctrl-clicking them into something

+1 for this, or something similar as my toolbelt just becomes a series of blueprints with one item captured anyway.

This has been implemented.
