No support from me, this doesn't sound really neccessary: Exporting something as a hotkey sounds rather useless, since you doesn't export often (And exporting via the menu isn't much more complicated)

Speaking of the "save level to ROM" box, it's pretty weird. I'm not sure why it throws up that confirmation box; I'm pretty sure it's left at the defaults 98% of the times.

and the address customization option doesn't even work.

the only thing I get from saying 00000 (which isn't mapped to the SNES address bus) is a message box saying "VERY BAD IDEA!!!"

Can't you just go into the respective mode, go to the top left corner, and start selecting everything with the selection rectangle? It doesn't take that long to get to screen 1F anwyays.

...that's the way I'd do it anyways

It's the only way in LM to save a level to a different level number. I suspect that's all that people use it for these days.

"A very bad idea"? Oh yeah, I remember that message. But the last version of LM that still had it was... 1.65?

While the address field is a bit of a holdover from LM's early days, it still works. But LM will only save at the provided address if:
-it actually exists in the current ROM (or after the 1MB expansion, if that option is on).
-it's in the expanded area of the ROM.
-there's enough space there.
-no other override takes priority (like for example, the new "prefer saving in 2MB+ ROM area" option)

how about a dialog box that appears when you have a certain amount of objects in the level?

Isn't there already a way to see how much ROM space it takes? That's infinitely more useful than how many objects are on the level.

Yes, I think so too.Why not move it to a separate menu item?

(And I still can't see any reason to let Ctrl-S map to something that doesn't act like the save button on the toolbar.)

With that many exceptions, the lack of error messages on failure, the 2MB+ favoring option making LM favor the locations that makes the most sense, and the fact that 99.9% of the users wouldn't care anyways, is that option even useful anymore?

It exists in private builds, but I haven't found anything like that in public builds. I'd guess FuSoYa thinks it may confuse the less technical users too much to keep it in the public builds (the less technical users won't find any private builds, so they're not a concern).

What? LM 1.72 doesn't exists. Or it's another private build?

Just a suggestion, you know how ZSNES makes things brighter, how about have a function to make LM as bright as ZSNES that way you can spot palette problems with Zsnes.
