Although the previous hatch used is sticky, is isn’t highlighted in the dialog so, in the case of ‘Solid’ the pattern has to be clicked to ensure you don’t have a different pattern set, which looks solid due to a small pattern scale.
For common drafting work, the default hatch pattern spacing is tiny by default. If there was a standard hatch sized to match the hatch pattern scale, it would take the guess work out of sizing hatch. Also a standard hatch set up at 45° would speed things up.
How useful it would be to have a match button at hatch creation time
Some other wishes:
Trim to hatch.
Option to change linetype of hatch, ByLayer or ByObject.
Hatch mask, same as text mask.
Checkbox in dialog to set history for hatch.
