Comment 9 for bug 1649183

There are quite a lot of misunderstandings in this bug report and discussion:

- Firstly, this is definitely a regression, though I'm not sure on the best approach forward from a UX point of view. It's confusing to have two methods of filtering, IMO. This needs thinking about.

- Secondly, that Python code was never removed, just deprecated, and it's listed explicitly in both the settings documentation and the release notes that you can just use the existing ones, so I don't really understand why you've stayed on Liberty. For the sake of saving you time, see https://docs.openstack.org/horizon/latest/configuration/settings.html#angular-features and set "images_panel" to False.

- Thirdly, I really loathe attitudes / suggestions like "Would be good to have a test system with say 150 images so these bugs are found before release" and "It's a real shame when really useful features are dropped". You're obviously correct; having huge testing systems would be great, and we don't drop features on purpose, but regressions happen on occasion. This is why we have weekly meetings, blueprint reviews, code reviews, and a fantastic team always helping and supporting on IRC. If you don't have the time / money / inclination to contribute to Horizon; thats fine; but please don't demand our time and money in return. A large proportion of Horizon contribution these days comes from people working well beyond the time their companies are paying them for; drop by IRC sometime and see how many people are online at >10PM in their time zones.
