Thanks for your proposal!
So far, we have no plans to add some switches for displaying indicators that are available in the tooltip (speed, start time and etc.), since previously none of the partners ask us to do this feature.
Please tell me why you want to disable this information? Why displaying, for example, speed information might interfere your clients' use of Locator?
I would also like to clarify the following: would you like to turn off of the display at the stage of creating a link, or it would be more convinient if it could be done as with the disabling of the unit name or the movement direction arrows (see screenshot below).
I will wait for your answers and interest from other partners.
