I cannot find information in the SchematicEditor manual, Libraries section, about creating my own library. The "add library" button in Components only selects between existing libraries, does not offer a "new" option.
I want to create a process technology specific library with BJTs, capacitors, resistors, diodes that map to the technology's SPICE models and correspond to specific device layout GDSes (or a bundle of fixed geometry layouts in a single reference GDS, for reuse).
I saw the video where subsequent steps of library editing are shown, but the initial creation was skipped over in favor of an existing library.
Making an empty "Devices.lel" file suffices for the "add library" to open it.
Now I find there is no grid shown in the symbol editor and I can find no mention of how to turn it on, whether it's possible, what the schematic default grid is or how to know that they symbol grid is compatible (if there is any adjustability). Certainly symbol grid needs to be the same as schematic snap-grid, or an integer multiple. But where's that set and how's it displayed?
Can find no way to alter text size or line weight in the symbol editor. "Edit" does not offer these options.
There appears to be no way to modify a created symbol shape element once placed - no stretch function, no properties other than color.
Zoom-in is limited and difficult to finely position vertices, cannot zoom in enough to get grid-snapping to be conveniently larger than mouse-movement resolution.
Save / Save-as from the symbol editor wants to save in .les (schematic) format. Saving it, does not make the symbol I created appear in the library list - only "new component" is shown. How is the library's contents updated? What makes a .lel file, a library besides its naming? How is a library "opened" for editing, management of contents other than the
In the library "Edit Component", Symbol only lets me choose from "empty symbol" and "noname". There is no provision to copy / import from an existing symbol drawing, nor search for one. There is no data copy / paste that I can find, although save-as of an existing symbol can be done as a start.

To create a new schematic library just create an empty new file with the *.lel* extension.
The schematic symbols works gridless and just uses snapping. If you create new symbols just make sure that the symbol size is similar to existing symbols to make the snapping / virtual grid work. If the symbol size is to big or the distance between two placed devices is to large the snapping will no longer work.

I see in the schematics "Dialog" > "Setup", Display>drawing there is grid settings but they are grayed out. I find that ctrl-G, shift-G seem to affect the snapping but I would like to be able to display and to set the grid for schematic drawing. The "G" bindkey evidently toggles grid display in layout mode but in schematics, places a ground symbol instead.
How can I turn on, set and lock down grid display properties?

The setup dialog for all windows (layout/schematic/3d view) are identical. Options not available for a windows are disabled when opened from this window. As the schematic does not use any grid, the grid setting are disabled.
