QOL Inserters slow with mixed items, and don't show all filters

[judos]

Some things that I found:

- Inserter have 5 filters, 4 of them are shown in the alt-view. Can you show the fifth in the middle as well?
- inserters become slow if they need to switch often between items. e.g. inserter grabs one-item, then waits a second (?) for matching item but there's none. Ability to reduce the time? Checkbox to say make it optimistic such that the inserter doesn't wait


Let me know what you think and if anything is possible that would already be cool

/edit: I'll move these suggestions into other threads, sorry for the mixed things..
- Placing underground belts over existing belts on a platform, where the belt is already full of items, deletes them? Place them on into the underground belt?
- Set max speed to platform via signal? As it's currently difficult to calculate the transformation between width+weight+fuel -> acceleration + speed of platform
- Maybe set max-throughput for pumps by signal? Currently I enable them x-ticks per second to control fluid throughput, but UI flickers terrible when hovering over the pump now
- Drag&Drop item requests from one logistics request group to another? I find it useful to disable certain groups sometimes, but it's annoying to remove item and add it again in another group
- Right-click on item slots on a platform should grab half a stack, therefore giving the ability to control precisely how many items to drop, right now I can only drop full stacks onto a planet, right I can request any-amount via the requests on planet, but it's annoying for one-time items
- decider combinators show the condition with green background if it is met. Can you add this to the signal condition ui on inserters, buildings? sometimes it's non-trivial whether the condition is met or not. e.g. 1k < 1k (can't see exact count), maybe the condition is fine, but it's waiting for items etc...
- ability to count items in logistics system without counting those inside buffer chests. I like spreading buffer chests but i need to produce enough so the buffer chests can actually fill, and i tend to add more buffer chests over time, so can't set a fixed amount...

This can be solved already this way:
Connect a circuit wire between the inserter and the belt piece under the inserter. Set the belt piece to read (hold). Set the inserter to set filters and whitelist.
This way the inserter will grab items as long as there is one on the belt piece and starts swinging immediately if the item(s) in hand isn't also available on the belt for pickup any more.
