When dragging an item to another section in the tree, the main window switches focus to this section when you hover over the tree list which is very annoying.

The search box in the upper-right corner clears when you switch to a different section in the inventory. It should remember it's state so you can search for an item and then just click through the sections in the tree, searching for that same item in each tree category.

The tree view uses up far too much screen real estate, a tabbed view would be far superior. Perhaps make it an option so you can choose to use whichever style fits you best. While you're at it, adding tabs to the ship maintenance array that could each be configured for use by a different pilot would be awesome, maybe even allow you to partition off an amount of the total storage capacity so that you could chose to have 2 equal sized tabs, or maybe one tab that is 50% and two other tabs each 25%, etc.

Stacking Items takes way too long.

Make each section remember it's preferred view settings. I want to see my ships as icons and my items as a detailed list without having to constantly push the button to change it.

I like to have my cargohold open in a small window in the lower corner of my screen while flying in space. I don't want other windows to default to opening to this window. Allow a way to seperate a section from the tree view and pin it in place so that it always opens in it's preferred location. I don't want to have to shift-click everytime I want to loot a wreck or something. Maybe allow a way choose whether your default action is open in a new window, or open in the same window.

I have given this new inventory system a chance. I've been using it and feel more comfortable with it now than I did at first. I didn't want to just start griping right away without giving it a fair chance first, however the old inventory system was far superior. Every task you do in the game requires the use of the inventory system and such a fundamental change to one of the core components to the game should have been thought out much better and thoroughly tested before it was implemented. The feedback on the forums about this system while it was on Sisi should have made it clear that it was not ready, yet it was pushed through regardless.

This new system has made me change my gameplay style greatly. I can no longer stand to use the inventory system if it can be avoided. This has cost me a great deal of isk as I no longer want to do any ratting and looting/salvaging, I no longer enjoy trade as it takes much longer to accomplish the same thing. I have had to occupy myself with pvp mostly for now, but without being able to do the tasks easily that I used to do in order to support my pvp habit my funds are dwindling and I'm seriously considering finding another game. My account expires in October. I guess we'll see how I feel about it when October comes around.
