1. A method of performing electrical stimulation programming, the method comprising:

  • in response to a plurality of electrodes being in an unlocked state, automatically allocating an electrical stimulation substantially evenly among the plurality of electrodes;

    in response to a user engagement with a first electrode of the plurality of electrodes, putting the first electrode in a locked state, while one or more second electrodes of the plurality of electrodes remain in the unlocked state;

    while the first electrode is in the locked state, allocating a first fraction of the electrical stimulation to the first electrode, where the locked state of the first electrode at least temporarily fixes the first fraction of the electrical stimulation to the first electrode such that the first fraction is user-adjustable but cannot be automatically changed;

    in response to the first electrode being put in the locked state, automatically allocating a respective second fraction of the electrical stimulation to the one or more second electrodes, wherein the second fraction is a function of the first fraction and a total number of the one or more second electrodes;

    thereafter adding a new electrode to the one or more second electrodes or deleting one of the one or more second electrodes, wherein the adding or the deleting is performed while the first fraction is still at least temporarily fixed to the first electrode;

    automatically adjusting the respective second fractions in response to the adding or the deleting, wherein the automatically adjusting is performed without affecting the first fraction of the electrical stimulation that has been at least temporarily fixed to the first electrode; and

    while the first electrode is in the locked state, adjusting the first fraction of the electrical stimulation in response to user input.
