Trick to remove is to delete the .thumbnails folder and create an empty .thumbnails file instead.

Also, an empty .nomedia file could be used in specific folders not to be picked up by the gallery.

Properly eject Android device after using ADB
Android uses ADB to communicate with physical devices and emulators. To
properly disconnect your phone first stop the ADB server and then eject
your device.

Making Android apps System apps
Used Link2SD to to that.
However some apps with libraries will fail unless the libraries are copied to /system/lib, e.g. libchromeview.so for Chrome. Easy to move from the APK files, or from the user apps before they are changed to system, located at /data/data/apps.

TouchPal language pack download
For some reason TouchPal X just failed to download the language packs.
I've used "Shark for root" to trace that it was downloading it from
http://ime.service.cootek.com/international/language/v5452/default/RussianPack.apk
but something must have been going wrong. Simply downloaded on my PC and installed on the phone.
Edit: this was likely due to /mnt/sdcard permissions/ownership incorrectly set in Link2SD mounting.

Link2SD using Internal SD card space
Requires rooted phone.
/system/etc/install-recovery.sh file created by Link2SD using external SD card with 2 FAT32 primary partitions:
modifed file:
The GID of 1015 is sdcard_rw, read/write group id. Otherwise 1000:system would not allow normal apps to write to /mnt/sdcard, which is also mounting the same partition - for some reason this affects its permissions/ownership also.
Note that with SD card being FAT32, it by itself does not store any permissions and ownership - the mounting point determines those.
If creating this file manually, /data/sdext2 folder must be created too, with RWE-R E-R E permissions, Owner ROOT and Group ROOT.
Taken from http://www.modaco.com/topic/356349-using-link2sd-to-use-internal-sd-as-extsd/
UPDATE: The permissions are still somehow being applied, specifically to /mtn/sdcard/Android/data/ program folders, without giving them write access. Didn't bother trying other things - just created a ext4 partition on the external SD card.

android internal SD card format
I've formatted the internal SD card on Windows computer. After that the phone (Android 4.0.3 ICS) did not recognize it. The phone is rooted and doing format from the shell (adb shell, while connected in CWM recovery mode) solved the problem:
Need to know the exact partition though - in my case mmcblk0p19. Then the /emmc mounted successfully.
busybox mkfs.vfat /dev/block/mmcblk0p19
