Strongly agree- for PPC advertisers, being able to export all ads in a CSV for a particular keyword would be incredibly useful (mainly for building new adcopies).

The ads data is far superior to SEM RUSH. If you do give the option to export all ads, you'll get way more PPC advertisers using/paying for Ahrefs, who probably use other tools currently, and can market Ahrefs as the premier PPC research tool (as opposed to SEO, which it's more well known for). At present, on the ads history tab it displays 10 results per page- for most queiries, there'll be often 50+ pages of ads to go through and manually copy (there's no export function even for the 10 ad results on each page) which isn't practical.

Ultimately the ads beta is hugely encouraging and with the addition of the above, could really make an industry leading tool!
