The Toolbars, Custom Toolbars, Preferences, Fibo preset , ....(so many) are stored in the config.json in :
(Mw dir)/workspaces/(name of the workspace)/config/config.json. (Mw dir = .motivewave for Linux do not know for Mac,Windows)
And it's a problem. A better solution is to separate preferences (ex: backupFolder , domHistoryLimit .....) from the others , Toolbars, custom Toolbars , Fibo preset , bar sizes, bar Size selector ......
A must will be a file for each type of config, ex : bar sizes, bar size selector , so you can export only the necessary config you need.
It's a problem because the format of config files is json and it's complicate to isolate json file.
I have a corrupt config file (can make crash my text editor, mw can be up connect to rithmic but no data on chart) and impossible to manualy isolate useful config from it to create a new clean workspace. So i have to manualy recreate all fibo preset, all custom Toolbars, toolbars ......
I will test the repository config but i suppose that all useful config will go all in "Include Preferences"
