Quite the humble brag, though imo the only pure QOL mods included are Even Distribution and Squeak Through (which I hope still respects the squeak_behaviour = false property from the current Squeak Through mod), and maaybe Far Reach

Here are some more QOL features you could try to implement, from Picker Extended Reborn and Picker Complete Feature Pack, in order of preferred priority:

• Start with Alt Mode enabled
• Automatic Inventory Sorting
• Belt Brush (allows placing multiple rows of belts at once)
• Belt Brush Balancers (related to the above, allows scrolling through common belt balancers of the appropriate sizes)
• Belt Reverser (reverse an entire line of belt with the press of a hotkey)
• Item Count (shows the full item count from the player inventory instead of just the amount that can fit in the cursor)
• Automatic Ghost Revival (when hovering over a ghost entity with the item in cursor, automatically builds it from the cursor)
• Quick Craft Hovered Entity (hotkey to craft the entity being hovered over)
• Auto Deconstruct (automatically marks mining drills for deconstruction when the ore patches are empty)
• Wire Cycler (hotkey to cycle between red/green/copper wire in cursor)
• Planner Cycler (same as above, but with blueprint/decon/upgrade/etc planners)

(there are other QOL and QOL-adjacent features contained within those mods, but these are the most important ones to include imo)

Just today i rewrote some functions to achieve better performance and i was thinking... Isn't this mod too small?

Thank you for making the research so much easier. Not promising anything, but i will try to implement most of the features you suggested.

Will keep updating.

If it's actually more efficient than the original implementations, I would very much love to see this mod with all of the QOL features.

Even my own implementation of Picker Extended Reborn is almost entirely based on a pre-existing implementation and hacked together into a workable state that could probably be done more efficiently

I am trying to deconstruct each feature and then re-do it in my own code and in my own way for the best performance. Thus from there is the feature for enabling everything through settings. If you want only some of the features the mod does not care about any of the other stuff and don't cache functions you disabled in the settings (maybe i will change the default behavior to false state, so people can enable their "best mods" on wish, it will load more quickly).

For instance, my implementation of Even Distribution Lite is about 35-40% faster after tests on my rig, than the actual mod.
The squeak through is really bare i admit it, but it is so fast you don't even see it in calculations in-game (basically changing base hitboxes before the game even starts :D)

So yea... I will do my best to make it fast, optimized and well packed in future!
