I would like to submit a bug report. When I came across this bug initially, I did not think it was important enough to be included in MCP, but I have since seen it reported by a couple of other people(http://www.uesp.net/wiki/Morrowind:Level#Bugs at the bottom of the page, and http://www.gamesas.com/index.php?/topic/1082396-unable-to-get-100-strength-with-5x-multiplier-and-strength-currently-at-95/) and seeing as MCP has started fixing cosmetic issues, I thought this gameplay bug too needed mentioning.
This will be fixed in the next release of MCP.
What about make the inventory icons larger in size?
It would be cool get those icons at higher resolution as 48x48 or maybe 64x64, rich in detail and colorful.
No, it's not as simple as just changing icons. I would have to change layout, button size, window size for the barter, tooltip, enchant, recharge, repair, and inventory windows, otherwise things will overlap or look unbalanced. It is too much work for something that doesn't cover the whole player base.
Another annoying thing is the duplicate items on dirty saves. For example a new mod that moves a NPC one millimeter, then that NPC will appear twice (only if the npc was previously shown and the game saved).
It already fixes this. Did you even test it?
Something maybe related that I'd really love would be a way to disable the 3D person automatic camera "bumping" away from a near object, it causes frequent visual glitches when riding my guar (and I think possibly in most situations when player position relative to a near object changes by small amounts frequently)
It's possible, but it will cause problems. In interiors there is a lot of overlapping geometry, so you are likely to lose sight of you character if you swing the camera through a wall. In exteriors there may be problems navigating daedric ruins, forts etc. when you need a clear line of sight. It needs a lot of testing for which conditions are suitable for turning it off.
The issue is that if you use either the console or a scripted version of PlaceAtPC while in 3rd person view, the item is placed at 0 distance, no matter what distance is called for by the script.
I'm trying to fix it at the moment.
What would also be neat is that the head follows the direction you face in 3rd person, vertically.
Not really a bug fix, nor an adaptation of existing code.
I would like to see something like "Spellmaker multiple effects" function for Enchanting.
Can you make an option to choose suitable magnitude? I personally prefer having limit of 1 000 while 250 is enough for my friend.
Multiple effects doesn't work so well with enchanting because of the doubling of points use when you add another effect; less than useful but I can try and figure it out. You will have to accept the compromise on the spell limits, it's technically more complicated than setting one value in the code.
