Search option for custom variables in tests

While we have a big dialog box for insert an existing component and an option to search for a specific one, we don’t have anything similar for the variables.

To get a custom variable you have to start typing {{ to get a dialog box opened. That for itself I think isn’t the best solution, perhabs get the option use custom variable added so it’s not under use custom selector.
Second the dialog box is a miniature one and don’t have any option to search for a specific variable.

In our case if all custom variables are added, there will be over 100 custom variables. It’s impossible to expect from someone to scroll and read through all those variables to find the correct one. As for now we have to open the variables in a second tab, look in that big window for the right one, click on it, copy the description, go back to the originally tab and paste the text.

Why not open a bigger dialog box and add a search option? It would make things so much easier
