W can place tiles under existing buildings, not being able to upgrade them is illogical

But nothing is flashing

TL;DR
Platform requested item inflight indicator
What?
When item requested by platform is iflight (left planet but not yet arrived at platform), if player manually sets platfoM to go to another planet, it will not go untill item inflight arrives. This is a bit confusing. We need a good indicator why ...

TL;DR
Allow upgrading requests in blueprint (to change quality of requested items)
What?
Currently we can use upgrade planners to upgrade entities in blueprints. But we can't update requests in chests. If we upgrade any turret that gets ammo from the chest that way, if we want tu change the quality ...

On mouse hover on logistic request in rocket, if i is fulfiled (even partrially), items in the store gain yellow(ish) highlight, and you have popup describing the request.

For a request that was partially fulfilled, while you are hovering (and popup is visible), if new items fullfiling that request ...

TL;DR
Signal display in platform list
What?
Add possibility to choose a signal from a platfrom (and if value should be displayed) next to a platform name in platform list
Why?
Will help managing spaceships (ie if they are ready to do something, etc.)

TL;DR
Path length visible on Transport belt circuit connection
What?
When there is a Hold (all belts) circuit connection, it would be usefull to see the total path length (including what is "under" underground belts).
Why?
It would make creating circuits based on belt capacity easier.

I propose a competition of some kind: fastest spaceship for a given space route
Rules:
1) unlimited startup time (to grab stuff and produce starting fuel&ammo)
2) any quality you want
3) can't take any damage
4) must go there and back

To be discussed: allowed tech level for repetable military ...

If I set up my building to produce specific quality items and put quality module(s) in, will it produce (given chance) higher quality than set up?

Let's create some lore

When hovering with mech armor over a rocket ready to be launched from the rocket silo, tip of the rocket is drawn over player, while rest of the rocket is drawn under player.

Organize Surfaces list so platforms without means of propulsion are shown next to planets they are orbiting, something like this: And maybe add some means of organizing flying platforms by hand

"Show mouse and keyboard control hints" setting does not show all working key bindings when in vehicle (ie for shooting, etc.), it shows only:

Foundry (research) wiki (and Factorio) says that it triggers on producing Tungsten Carbide, but I had to mine Calcite to trigger it.

Where placing blueprint ower water, show how much landfill is needed.

This also happend for other buildings when their placement is blocked either by another building or a cliff.

Factorio does not know how to lowercase/upercase Polish letters (ąćęłńóśźż), so when I search for coal (węgiel in Polish) it does not work if I use uppercase ę (Ę).

When blueprint with mining drill is placed over water, even if mining drill will not be placed (due to lack of resources in that specific location) landfill is placed regardless

Expected behaviour: when placing blueprint, do not place landfill if there would be no building over it becaouse of any ...

Step #2: fussion trains

So if I (for example) lauch big blueprint with (for example) plenty of solar panels, to keep with it I need to produce 3 solar panels per tick?
