The TweetDeck desktop client has seen a major overhaul, with a move away from Adobe Air and a whole new approach to accounts and feeds. It’s all very snazzy, with a blue theme and some very welcome touches: I’ve long loved Tweetlist’s highlighted usernames and links, so they’re very welcome here, and tweet boxes that scale dynamically to the length of the tweet are long overdue. That’s the positives covered.

On to the not-so-positives. The tweet box now pops up and steals the focus until you close it. A small change, you might think, but I regularly half-write tweets while I keep reading those of others, then react as I go. Sometimes I leave a tweet for ten minutes to decide whether it should really be sent (it usually shouldn’t). This prevents that, and it’s totally unnecessary. You also can’t send a tweet using Enter, and if you think you can go to Settings and change that, you can’t – it’s been pared back to the idiot-proof basics.

Tweets are now labelled with the number of days ago they were sent, rather than the actual time. That might not sound much, but I can think of many occasions when seeing a tweet was sent at 12pm or 12am made a big difference to the way I interpreted it. Every tweet now gives pride of place to the username of the sender, rather than the tweet itself. And unsurprisingly, the range of URL shorteners and photo services is cut right down, with Twitter’s own now the default.

It’s that oversimplification that constantly jars. When I first installed it and synced it up with my TweetDeck account, I was presented with a Home column of tweets, a Me column of mentions, and a Messages column for those all-important DMs.

But something wasn’t right. There were DMs I hadn’t sent or received. There were people in my Home feed I didn’t follow.

Now, I don’t just tweet from one account; I have three. I’m sure many people do the same, be it personal and work accounts, websites they run, or just a desire for different accounts for different needs.

New TweetDeck had taken it upon itself to make assumptions about my three accounts. The Home feed was taken solely from the team’s @pcpro account, which it had randomly assigned as my default despite there being seemingly no option to set an account as default. I’ve tried deleting all three accounts and adding them in a different order, but it always becomes the default. This also means every time I type a tweet, it assumes I’m sending it from that account, which I rarely do; if you see @pcpro tweet about its hangover on Saturday morning, blame TweetDeck, not me.

The Me feed and Messages column, on the other hand, automatically roll all three accounts into one, with no proper indication of which tweet came from which account. I don’t want to read my editor’s correspondence with our lovely readers mixed in with my own private messages; it’s confusing, a little bit scary and raises the potential for embarrassing blunders. I have three separate accounts for a reason; the decision to bundle them together should be mine, not TweetDeck’s.

Most of this can be fixed by simply deleting all of the default columns and creating new Timelines and Messages columns for each individual account, but to a long-term user like me it seems a perverse way of doing things. Don’t get me started on the way every link and photo now sends you to the browser, or clicking a tweet opens it over that column in the style of the Twitter web interface.

It’s not terrible, and I’m sure I’ll get used to some of its quirks. But for me the new client takes away much of what made TweetDeck so useful – namely the flexibility and control – and replaces it with much of what makes the Twitter web client so annoying. I don’t like the Twitter web interface, that’s why I use TweetDeck. Or at least it was until now. The former buying the latter means that distinction is only going to get narrower from here on in.
