On the whole 2.5 seems like a good step forward, however there are a few areas where I thing WordPress has leaped backwards.
1) Widgets/Sidebar screen - its just awkward and cumbersome to use now. What was wrong with the old layout? Now I have to select sidebars to switch between them, its not clear what has been used and what hasn't, widget options page is nice and scrolly - but not practical. Expand a widget, scroll down to save then you have to scroll back up to the sidebar again.
2) Post editing screen - what a mess! It now takes me 4x longer (not joking!) to create posts now.
2.3: Fill in title, enter post text, scroll down and start upload of picture (slow connection) while uploading assign tags, categories and custom fields. When image uploaded, copy path to a custom field and save.
2.5: Fill in title, enter post text, open new window to upload image, wait while uploads, forgot to copy post title to clipboard so close window copy post title, reopen window, find image uploaded and change details. Remember to copy image path to clipboard, close window, fill in custom fields, save post.
I aim to post around 6 posts per day. I just did this, generated my own custom thumbs (I use a fixed size, cropped and photoshop filter which I upload seperatly via ftp) uploaded and checked my drafts. Expecting to see my 6 posts, quite sup surprised to see 26! 6 posts + 20 "Draft created on April 1, 2008 at 5:38 pm"
Can we at least have the old image uploader back?
Just my .02c, I like 2.5, I just feel that it needs some refining.
Keep up the good work
