It is usable. There was some big overhaul of the modbuild so the toml files created with the tool were no longer relevant. Effort is spent working on a new version planned for the next modbuild release.
3 Features I would like added if they are not added already. If they are already added I would appreciate support finding them.
1. A setting to tell HoloPatcher to not make Backup and Uninstall Folders. With ModSync, I do not really need Backup and Unistall Folders. I wrote some simple .bat scripts to delete them in my mod directory and subdirectories as a temporary solution to save space, but I would prefer not to do the read/write in the first place. Backup and Uninstall folder is essential when manually installing the mods, but with mod sync I just do a full re-install so easily. It would also make the process faster because now those folders do not need to be created and files do not need to be backed up. I have tried the original method of editing change.ini that TSLPatcher used, but HoloPatcher appears to be set to do this by default. This may be something more to address with the HoloPatcher.exe so I am going to reach out to the developer too to see if he can release an alternative version of Holopatcher that does not backup/unistall or can add the feature to read the change.ini.
2. Make defined windows borders if possible. The program works fine without them, but sometimes when I am in the thick of managing a bunch of mods the window slides around.
3. I have been managing the mod install order by numbering my mod folder then adding them to modsync. I realize there are a bunch of features in Modsync so that the actual add numbered order is irrelevant, but I just find it confusing to manage that way. I prefer it in the numbered order that I install it in. When I press "add a mod" the mod is added to the end of the list creating a new entry in the toml file at the end/bottom. I would like the feature that inserts the entry based on what mod I have currently selected. I suppose beneath the mod I have selected makes the most sense but either insert the new mod addition above or below the mod I have currently selected. Perhaps a separate insert button or just make this the default way to add mods. My temporary workaround has been editing the toml file in Notepad++. It is easier to copy and paste the entries than it is to move them up or down with the arrows in ModSync unless it is only a few spaces needed to move.
