I just cannot wait for an update on color. That is an update that allows players to customize the colors and gas giants, gas giant band colors and quantity, cloud color, water color, atmosphere color and star color as well. Adding color support for all my requests above, will make it much easier for users to be more productive when creating custom objects and simulations. No more tedious file modding would be needed if developers make a full update on color.
In addition to that, I would like to be able to create planet by importing custom textures, such as importing downloaded texture images from Google.
Planet grids is also a feature that I am waiting for, but for me it is a close second to me. Planet grids would be very useful so that ground surfaces would become much more detailed. For example, the ability to see different elevation terrain such as mountains, valleys, and ocean floor. This update would enable various temperatures and seasons, seasonal changes throughout both the northern and southern hemispheres of planets.
I very much hope that all those features and updates will be released this year in 2019. By the way, developers must make a 2019 roadmap to show what they are working on this year, what will be added and complete this year as well as what's coming next for 2020.
There are also many, many bugs in Universe Sandbox 2 that were never fixed. The worst of all bugs is the "water freezing glitch" and the disappearance of stars when editing their surface temperature and luminosity. The disappearance of gas giants when colliding with rocky planets is also a terrible glitch that must be fixed. The problem is when developers release new updates it create more and more bugs rather than fixing previous bugs known in older updates. Developers must be more careful and thoroughly test out updates before releasing them.
I hope that the next update will be something like a Service Pack update that fixes all the bugs and glitches in Universe Sandbox 2. At the moment, this simulator is one of the most bugged games I ever encountered. Please make the most as you can this year in 2019.
Good luck on your development adventure.
