No need to bump or repost at all. I record every suggestion on the forum until we're able to take the time to carefully review them. We're trying to be fair and go through them all in chronological order, except for extremely popular requests which may get prioritized and be added sooner.
If you see other plugin requests made after you get added, and this one is still not, you can certainly feel free to ask about it or repost. It may be a while, so your patience is appreciated. Also I'd prefer one suggestion per thread unless they are related plugins, since it's easier to keep track of that way.
In addition, plugin updates are always done first, and any extra time is spent on reviewing new plugins. Hope that answers and clarifies any questions you had about the general process.
