- Choosing a file from a directory of mkb files, and assigning it to a knob. This is done in XAL knobs by the Open File dialog, which opens a dialog onto the Default Folder. We can also put the files on the Web, accessed through the XAl knobs web page.
- Displaying the contents of some knob files directly as a button push. Contents of the file are displayed by the Knobs app.
- Organizing mkbs that have a common subject, into groups on a panel or onto different panels. XAL knobs does organization by Knob Groups.
Comparing non-GUI functionality
- In XAL knobs, only a single linear coefficient factor is available as the "knob" value factor; ie no power series or sine/cosine factors.
- SLC mkbs always "perturb" magnets and klystrons. In XAK knobs, no special action is taken at the level of the GUI, the method is dictated by whatever the PV implements.
