Even though I preferred the 1989-1991 idents, I did like the 1991-1993 'Next', 'Later', 'Tomorrow' continuity jingles. You could tell Central was in control coming up with so many variations of these and music. Even though the sun and moon imagery took centre stage in these inter-programme jingles, they weren't used at all after 1993 even though they were still part of the main logo, which was a shame.
Central did do presentation very well, and I wonder if that harks back to the ATV days. While some of the idents may not have aged that well, or at all - the cohesive yet different design of all the elements was a major plus.
CITV was no different, and having such a wide array of styles available all meeting a similar brief was Central's forte - wasn't one of their subsidaries a branding unit that made idents and graphics for indies and smaller ITV regions?
