We use Discord as our primary support channel. It's a convenient platform for various reasons and it's also easily accessible to the community
(most people have a Discord account, but not necessarily a GitHub account).
Basic information is publicly available on the
EDHM_UI website.
You should know that EDHM is a mod that allows you to customize your interface.
EDHM files are placed in the game's directory so that the game can load them at startup.
EDHM configuration files are .ini files that can be edited using a text editor like Notepad to enter your custom settings.
Since this is not very intuitive, there is a user interface that allows you to edit these .ini files using a more intuitive interface than a text editor (EDHM + UI = EDHM_UI).
Before, EDHM_UI only requested administrator rights during installation, but it turned out that in most cases, EDHM_UI could not modify the EDHM configuration files because the program did not have write permissions in the game directory.
Remember that EDHM files are placed in the game directory so that the game can load them at startup.
To answer the comparison with EDMC, EDMC does not need to access the game directory unlike EDHM and EDHM_UI, which explains why EDMC does not require administrator rights to function.
It's this kind of mechanism that can trigger warnings with certain antivirus programs. Unfortunately, since EDHM must be placed in the game directory, we cannot avoid this behavior.
There is a paid certificate that could solve some of these problems, but EDHM and EDHM_UI are free and we do not accept donations, so it is not possible for us to invest financially in a certificate that is not a guarantee of reliability and security. We already invest a lot of our free time in the development, maintenance, and support of EDHM and EDHM_UI.
We prefer to offer EDHM and EDHM_UI for free and let users choose whether or not to install the program.
Regarding OneDrive, you should know that the EDHM_UI configuration files (EDHM_UI, not EDHM) as well as themes are stored in the user's documents, but it turns out that if OneDrive synchronizes this folder, the program can no longer access these files, as if they were not in the indicated location. There may be a solution to work around this problem, but we haven't found it yet.
For those who do not want to install EDHM_UI, you should know that it is possible to use
EDHM alone, but this means that there is no user interface to configure it, you have to do it with a text editor, there is no theme, no automatic theme change, no automatic installation, no automatic update. It's quite difficult to get started but it remains a possibility.
I hope I have answered all your questions, which I find legitimate. As we always say, the choice of whether or not to use EDHM and EDHM_UI belongs to the users.
