Amid the various large-scale changes at Twitter, the platform is also working on some smaller tweaks and updates, which may or may not ever get released, but could provide valuable functionality for many users.

First off, Twitter’s testing the ability to search through your Likes, so you can find out who, specifically, has liked your tweets.

That could help you glean more context when reaching out to someone, or just another way to understand who’s responding to your tweets.

And it could be particularly valuable as a research tool for marketers in understanding their audience and who they’re reaching with their tweets.

Twitter’s also testing a new way to filter your replies, which could be handy if you get a lot of responses to a tweet.

I mean, I’m not sure how many people are getting so many replies to their tweets that they need a filtering option, but for those that are, this could be a simple way to ensure you’re staying up on the most relevant responses and responders, to better manage your engagement.

Finally, Twitter’s also experimenting with new timeline settings, which would provide more control over your timeline and pinned lists.

Note also, in the middle screen, that Twitter’s developing an option that would enable you to hide your tweet view counts, which would provide another way to manage your activity in the app.

As noted, all of these are in test mode, with Twitter engineer Andrea Conway posting them for public opinion, before exploring further development. But they could be handy, and while they’re not game-changers as such (which may mean they get less priority), smaller tweaks and updates like this could be significant for certain users, and could make it easier to manage your tweet activity.

We’ll keep you updated on any progress.

Here’s the difficult thing with Twitter no longer having a comms department – now, there’s nowhere to go to confirm info about the app’s latest updates and features, and where each is available, etc.

Case in point – this week, Twitter appears to have launched a new in-stream boost option for tweets, which provides a quick and easy way to promote your tweet without having to launch a full ad campaign.

As you can see in these screenshots, posted by Jonah Manzano (and shared by Matt Navarra), the new boost option would be available direct from a tweet. You’d simply tap through, select a budget, and you would be able to boost your tweet then and there.

Which seems to be new, but also seems familiar.

It’s sort of like Twitter’s Quick Promote option, but an even more streamlined version, with new visuals and a new UI for boosting a tweet direct from the details screen.

So it does seem like a new addition – but again, with no one at Twitter to ask, it’s hard to confirm detail about the option.

But from what we can tell, this is a new Twitter ad process, which could provide another way to set an objective, a budget, and basic targeting parameters to reach a broader audience in the app.

Which could be good, depending on performance, and there may well be some tweets that you just want to quickly boost and push out to more people, without launching a full campaign.

It could also be a good way for Twitter to bring in a few more ad dollars, and it could be worth experimenting with to see what result you get, based on the simplified launch process.

If it’s available to you. We’d ask Twitter where this is being made available, but we can’t. So maybe you’ll see it in the app, maybe not.

Thus is the enigma of Twitter 2.0.
