Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Split definition of custom views: In the previous version the T7 and T3 custom views were defined using the same enum. As result an ID shift may happen causing errors in the selection of the big font views. The second reason to split the definition is that shift operations are used in uint32_t variable (limit 32). The total number of current views is 27 => splitting will avoid ID problems in case new views are added.
