It's great to have this resource [and at an affordable (pre-publication) price]. I do have a few observations:
- The "Visual Guide" that explains the structure of each lexical entry, including symbols like the diamond (♦) or the "black right-pointing triangle" (▶) is lacking (though it is printed in color inside the cover of the print edition). For those interested, the visual guide is available online at https://brill.com/fileasset/downloads_products/34732_Preview.pdf.
- A greater concern is that these symbols are inconsistently placed in the text (in comparison to the print version.) See examples below:
This first is the image of the entry on agathos in the print edition of the GE. Note the use of the boxes and circles around the numbers and letters indicating different parts of the entry (green arrows). Notice also the use of the right-facing triangles that provide visual cues to breaks in the entry.

Now, compare that with the screenshot from Logos below. The purple arrows show that the main numbered parts of the entry get a bit 'lost' in the text. This is particularly the case with the letters in the outline (see green arrows). For instance, see the "a" in "good: a well-born, noble" where the "a" is in the same bold font as the text, while in the print edition, the "a" is enclosed in a box: 🄰. The right-facing triangles (▶) are non-existent (see blue arrows).

I do hope that further revisions of this lexicon will include these typographical indicators that make the lexicon more user-friendly. Perhaps it could also be enhanced in a way similar to how BDAG has been presented in outline form rather than in straight paragraph form.
