Make a mod which can break a blueprint up into independent slices. A slice is a collection of any number of entities that are interacting with each other in any way, directly or indirectly. Every slice can become its own blueprint. (Typically a finished blueprint is made up of only one slice.) Examp...

Thanks for the tip!

Make a mod that lets you save and restore your preferred logistic requests (for character, spidertron, etc) similar to the Quickbar Templates mod.

Add a new artificial cliff type in the style of a big compound wall.

Make a mod that lets you place a mini rocket and launch it to create a little fireworks show!

When driving manually you would not be able to choose some directions since you can at most go left (holding left when crossing junction), straight (holding nothing) or right (holding right when crossing junction). This would be an issue, but honestly a new S-bend would be well worth it. Please con...

Add a shortcut to navigate to the containing blueprint book. Currently there are 3 keys, all of which do the same (goes to the blueprint library top level): ESC E B I suggest making one of them go up one level. It could be a configurable shortcut. Related suggestion: automatically return to the cont...

I'm thinking of making a mod for a new rail signal type, and some other train-related stuff, but looking at the modding API is not giving me much hope. I would like to have the following APIs: Find best rail path from A to B Optional list of rail pieces or signals to exclude from the path finding Pr...

I did some napkin math. I've seen that electricity price cap in the UK is 0.28£ per kWh ( I used this source ). One would need about 1.786 kWh to achieve an additional cost of 0.50£, which, at 50W, would take around 35 hours and 40 minutes. I'm wondering how you can squeeze over 35 hours of Factori...

The Efficiency_module_3.png of the M1 is quite nice. A few years ago I got a Windows laptop with the intention of switching from Mac to Windows to get away from Apple's walled garden and anti-repair practices. Long story short, I'm still a Mac user because I couldn't get used to the way Windows does...

+1 for improving the filtering/sorting in the mod browser. It's currently too fuzzy and unclear why certain (many) results are displayed for a given string of text. Whole word matches in the mod title should be top results, then in description and then fuzzy matches (stemming?), but fuzzy matching n...

Just look at this screenshot from my game yesterday: chat-pings.png Can you understand who's pinging where? (There were more pings that aren't shown in the chat window when I took this screenshot.) It's not made easier by the fact that clicking on the chat link automatically hides the chat, and that...

On a multiplayer server I joined recently the host said he had enabled biters but we never found any (even after venturing out 1000s of meters). I made a copy of the savegame and grabbed the map exchange string and imported it into the new freeplay setup screen and confirmed there are no biters in t...

I've been thinking of a new type of construction planner which I've dubbed "Blueprint Planner". The idea is still very underdeveloped and half-baked (which is why I'm not posting this in the Ideas & Suggestions section), but I think it has a lot of potential in general and I'd like to ...

I suggest that when trying to place a blueprint and there are structures blocking the way, the error message when you click (without holding the shift key) should prioritize the fact that machines are in the way over any tree/rocks/cliffs (which can be automatically deconstructed and the blueprint g...

+1 for recursive blueprint book search.

Selection of messages would be nice to be able to copy and paste into a translation app...

Good point, but slot locking doesn't work when each leg in the train's schedule has different cargo (to maximize efficiency you can deliver ingredients in the exact ratio and pick up the products with one train instead of two trains each running one leg empty), or when transporting barrels (the abil...

Couldn't the logic be changed so that cargo wagons can't be interacted with for 1 tick after the train comes to a rest, so that the inserters get the needed signals in time? I don't think the current behavior makes much sense and making this change would be unnoticed by most players. Having to add e...

Thanks, boskid!
