That helps a little, thanks for suggestion
But that does not deal with the core of issue / inner-workings
And the fact that the ► drop down menu icon is far to the right while the beginning of the Filter Box is on the left [and that extreme right and extreme left if you are using an ultrawide screen] only ads to the annoyance - I either have a choice of constant [temporal] deleting of signs in Filter box or constant large moves of my hand for [permanent] clean up of the list. Either way- not comfortable
But how about such a new feature: ability to move up and down a filtering expression on the list of expressions that drops down when you click the ▼ icon? The user could simply highlight the wanted filtering expression [just like it currently works] but the instead of just clicking it with left button, click and hold it and move it up / down the list? That would be even better solution, as the user might want to bring from the garbaged bottom some still needed 2 or 3 old expressions
