Would be great to define a few hot buttons in the upper project windows with which several predefined timelines can be opened quickly.
Setup instruction:
In the metadata fields is a row "hotbutton" where predefined numbers are available in a dropdown menu. E.g. for 5 hotbuttons in total available in the dropdown you find the numbers 1 or 2 or 3 or 4 or 5. The corresponding hot-buttons are always visible in the project window in the upper space maybe right from the search field icon.
If I now define a two timelines to be connected to hot-button 1 and 8 timelines to be connected with hot-button 2 I can easily recall these timelines at once without searching. At a very big project with several edit-version this would help me a lot.
Recall instruction:
No matter how many timelines are open at the moment. When pushing hot-button 1 those previously predefined two timelines open. And when pushing hot-button 2 these two timelines get closed and the 8 timelines of hot-button 2 open. When deactivating all hot-buttons the initial state of timelines appear again.
