Web app: v2.1.0, improvements

(New:) Text content page, comments to sentences (yet without indication of scope), sentence token ID lookup;
(Changed:) Change of citation of sentence reading variants (permanent IDs/URLs can be guaranteed only for the sentence, not reliably for its individual reading variants);
(Improved:) Metadata on text/object pages complete, linking of text/object metadata with thesaurus pages, more consistency in metadata/link icons.

Text corpus supported: v17, unchanged

(Note: By mistake, only sentence comments from before 2015 are present in this corpus edition.)
