Absolutely, I can relate. You put in the effort, invest time to build a good product that would surely benefit the community – and for what? I actually enjoy using Opera and would love to support it with my tools, which, by the way, are all completely free for everyone and took a lot of time to create, only to have them ignored without a word. That really kills the motivation.
If one at least knew it was just a matter of time, or got informed about whether and what issue exists, that would be manageable. But after months without any reaction at all, it gets tough. A simple status update or a queue indicator would already help enormously here – at least then you'd know where things stand.
At least the community here seems pretty active, which I think is great. Other stores often manage reviews within a few days – it would be great if someone from Opera could chime in here and shed some light on this.
