The mod menu and the mod tools are the urgency! As a modder, I can't upload my mod correct on the new launcher.
First of all, you can't tell which one is the local version of your mod while using the new mod tool to upload, which cause a problem if you are updating your old mod. Secondly, new mod tool is missing the most important button "check this mod on the workshop", so you don't know if it will be updated correctly or just create a new mod which you have no intention to. Thirdly, you have to write down a new description to "light up" the upload button, no matter if you already have a much nicer mod description on the workshop page. And more scarly, any "description" you write down here while uploading will totolly overwrite your old descriptions. Thanks for my discretion, I create a test mod before I upload my actrual ones, otherwise my valuable descriptions will be gone forever considering I didn't back up the descriptions on workshop pages.
And there are much more issues, such like if you roll back to 2.3, any mod support 2.4 will disappear. And for that test mod I created, I can't get it down to access the mod profile picture that I prepared by the old way. Also there is a new "descriptor.mod" in the folder of the mod, the "supported_version="2.*.*"" be comes "version="2.4.*"", which totolly makes me confused.
