Blueprints should work as regular copy/paste/delete, not item in the game. Have a selection tool (may have more purposes, like show content of selected chests, or display stats for part of factory; may also have "Shift+click" to select objects individually, not just a rectangle). Then, You...

Minor issue. Definitely not game breaker ;) When I press Q over curver rail section, track orientation should be "carried" to the new track piece on cursor, according to some logic. However, this logic works only in 4/8 possible sections. https://snag.gy/Ogd3SZ.jpg Sections B, D, F ang H w...

Currently, nukes have kill radius just barely exceeding firing range, so it's easy to kill Yourself. Also, it's possible to use it accidentally inside Your base (i did it once, wrong mouse button pressed while shooting to chests. Chests were destroyed at least...). It definitely should not be a &quo...

Artillery should have another slot for remote device. It should not target anything automatically, if slot is empty.
Player just need to build few devices more if he want auto-targeting to work.

IDK if it's bug or feature, but Artillery should only target at known and visible on the map bases. Now it targets any base, even if it is on the black spot of the map.
It is illogical, that Artillery knows where bases are, while I, nor Radar, nor the Map do not.

FIrst, the BOTH tabs should be visible, one next to another, if inserter (or anything else) is in "connected" state. I had similar problem with stations...

This strange behaviour cause problems with some stations designs. If You want to switch tracks directly after Station, You may accidentally, unknowingly, place new tracks one tile to early. Sometimes it may lead to rebuilding entire station. I am "fixing" it, by placing chain signal first,...

That's a bug in my opinion. If there is Track Switch, You can not place eg. Rail Signal beyond some point, but You still can place a Train Stop. Train stopped at this station can not turn on that switch.

Guidance Computer. Building, connected with wires to radar(s) and Turret(s). Then, all unconnected turrets works as now, but others receives orders from Computer, based on Radar Data, and works as a team. All settings You do are in Computer (one device). You may connect more computers to different t...

Please add shortcut for locomotive switch. I want to enter, press "M", drive manually somewhere, then press "A" and drive in Automatic mode...

There are deffinitelly more things, that should have special behaviour when placed on the bottom cliff tile. Walls blended into mountain are perfect examples. Gates should also merge with the cliffs. Here's proposition for pipes and belts. https://forums.factorio.com/viewtopic.php?f=6&t=57356 Ot...

Yes it does. After upgrading boilers sizes they were overlapping each other, and still works...

THat's why I am not want to implement offset/shift/perspective correction. Would be great, but it's not necessary. I just want possibility to build underground belts and pipes directly on the tile already occupied by the cliff. BEFORE (ugly, unnatural, pointless, more space required): https://snag.g...

I think offset is not possible to implement in a intuitive way.
Whec Cliffs ends, there would be possibility to "match" upper belt from two different lower belts, so there would be lot of quirks and inconsistencies...

I always play with some own rules, like never landfill, never destroy cliffs, and always adapt to the nature. My Factories are fitted and blended into nature, around lakes and Cliffs, so this feature (not hard to implement I guess) could be beneficial, and is quite natural - that's the way Undergrou...

Offseting "lower" belt segment by one tile part is totally optional, idea is valid also without this: Allow Underground Belts and Underground Pipes to be placed directly at cliff (only the bottom cliff tile). https://snag.gy/HuK3ZC.jpg Cliffs (vertical) are always two tiles wide, so Why no...

Basically, secondary, optional "electric" network to nerf, buff or balance some game aspects. What is Computation Center Grid? It's simply copied, retextured and renamed electric grid infrastructure, working in very similar way. It may works slower (eg. 5-10 update per second) to increase ...

Full chest of green Circuits (10k items) would explode, and cover area of 100x100 tiles. Have a nice cleaning... Destroyed tank full of stuff... 3x more? I had once cancelled some crafting with full inventory. Player "exploded" covering whole factory with steel plates. I was cleaning it ov...

Also. If "lakes" have water levels, there can be level difference. If so, we can implement water turbines. One end sucks water (and lower the level), other drains, increasing water level. Once levels equalize, quite fast to avoid "infinite pump loop free energy", You must find an...
