Thanks! And yeah you have to manually copy them over (highlight all, copy over, then click skip all repeat items, or sort by date added and copy all new) but I believe you can set your splice folder to sync to a certain folder. If not- there is the option to do a junction folder if you really want to get fancy and have 0 maintenance on it.
Very similar process. If you installed them correctly, you need to locate where your plug-in is installed, then show FL where that folder is in your plug-in search scan prompt under the manage plugins>scan for new plugins action. Should be a little + on the left to add a folder search path. Do you know what I am talking about?
