So much… ok

- Multi-touch gestures support-dev - for iPad
Already in trunk (developer version; which means; next version). You can use it like an mouse hook.
- 4K resolution support (1920x1200 is actually the max)
not an good idea

But with the next release, we support 4k movies like VP9. Retina means, that the picture looks sharp if you scale it up 3x times

On The iPad, we make the max resolution.
- Custom interface (ex : show/hide fonctions in "Action part" ; Dark color scheme ; Color of the background)
Hm?
- Menu in "Accordion" style (Especially for the "Action menu" !)
Hm?
- Bigger points and lines in the "Way system"
Hm… I need my glasses too to see the points…
- A crash reporter with the logs sending (maybe ?)
It gives an crash reporter for the editor…
- Vis to remember the last window size when opening (full-size window at each start on mac is boring)
I know that i changed something… 4.1 ? Or simply delete / overwrite your config.ini in the ~/Library/Application Support/YourcompanyName/YourGameName Directory
- Fullscreen App support (for OSX 10.9+)
exists with 4.1 (retina)
- XBox360 Controller support (Yeah, it sounds stupid for Point&Click but it open the possibilities. Still no support on 2,5$ billion Minecraft which is Microsoft also...)
We test a little bit with controllers…
- Keyboard shortcuts layout... with shortcuts
Like: Alt+F4?

- Real-time player (modify the game while you play so you don't have to run the game each time you make modifications)
Hm? You modify the game if you give the character an baseball bat?

You mean an other thing?

- Sound FX engine (Real-time rendered FX like reverb/delay/compression/pitch/distortion/etc)
Very complicated… To make it cross platform

- Video "in-scene" (video playback inside a scene with custom size etc)
Full motion video

It wasn't possible. All FMV games playing and movie and simply have an event on an mouse position.
- Use the mouse-wheel to increase/decrease value number of the selected parameter (by 1, 10 or 100 defined in option menu)
We did not know, what exactly someone want's to to with the mouse wheel. We're developeing an engine. So, your part to do that. But don't worry. It's very easy.
- "Turn before walk" animations ; "End/Start walking " animation
Hm?
- To-Do List section (with a "Checkable" case)
Hm?
- Overhaul iconography to navigate faster thru menus and options (and to look more awesome)
The other dev's looks awesome too

(joke)
- Help section that redirect on Wiki
Cool and nice idea!

- Icon (PC/Mac) an cover of the game in "Game info" section (used when exporting the game)
An list was technically easier for us.
Lua Sockets dont work when I tried them.
You tried it with:
local http = require("socket.http")
?
I am sure it works. With the current VS.
That is a waste of work I think. There will be sooner or later a decoder for all formats...
We've a lot of decoders, which uses ffmpeg. But probably we support OGG & OPUS as audio, because ffmpeg have trouble with some formats on different platforms.
And if you are making an game it was better to use free codecs. (like VP8 / VP9 for Movies and opus or ogg for audio)
