1m73 72Kg 49yo speaking here
I'd say the suggestion (weight ranges) makes
*some* sense and anyway if it is implemented as the other categories you'll have the option to use to the usual LW / HW / any weight. That doesn't mean that competitions should have weight ranges beyond the classical LW/HW, but yeah, as a logbook tool it makes sense to me.
I actually have a minor suggestion, loosely related: on top of the usual age ranges (e.g. 30-39) you could have a range relative to your age, as in "your age +/-5y"). I'm 49yo, that would be 44-53. This avoids the potential "bump" when you change range (e.g. for me soon, going from 49 to 50).
I know there's the "custom" option, but that's less practical as you have to enter the bounds manually each time. The same could be applied to weights ("your weight +/- 5kg").
Anyway, we'd better spend this time training
