So if you’d like the parameter Reverb Time to always be the first fader or any have other parameter(s) that does not normally show up here to be visible, you can make it so.
While in Edit mode, for deeper programming, the Soft Row becomes visible for selecting another row of parameters for access to more of the plug-in’s under-the-hood divinity.
Depending on the reverb plug-in instantiated - I’ll use the Chamber reverb as an example—the Soft Row will have the button names: Input & Mix, Reflections, Reverb and Echoes. When any of them are clicked, sub-parameters faders appear.
For example, when Input & Mix is clicked, Mix (wet/dry), Diffusion, Shape, Spread and Predelay parameters become available.
If applicable, additional buttons above these sub parameter buttons will show up.
In the above example, Predelay (as do all delay parameters in all plugs) has a toggle switch for either Absolute (the fader positional value) or Tempo-based from a 32nd note to a half-note value predicated upon the session’s tempo.

It sounds more complicated here than it really is.
Know that there is the good ol’ Compare button to show the preset default parameter settings if you get lost in a wilderness of bewilderment.
Lastly, the Lexicon Native PCM bundle has its own comprehensive interface for managing, naming, and saving modified user presets.
As user presets are accumulated, they are listed in the aforementioned Category pull-down menu.
User presets are stored within the plug-in itself, instead of in the DAW’s plug-in folder, as usually the case.

This means that they, along with all the Native PCM reverbs, are available for other programs in your computer. If you sequence in Logic and mix in Pro Tools, you can keep the reverb sounds consistent across both platforms.
You could also share them (as XML text files) with other systems or between Mac and PCs. (Now that is cool!)
